Check Digit Verification of cas no

The CAS Registry Mumber 69808-76-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,0 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 69808-76:
(7*6)+(6*9)+(5*8)+(4*0)+(3*8)+(2*7)+(1*6)=180
180 % 10 = 0
So 69808-76-0 is a valid CAS Registry Number.

Cu(OAc)2-Triggered Cascade Reaction of Malonate-Tethered Acyl Oximes with Indoles, Indole-2-alcohols, and Indole-2-carboxamides

Mao, Peng-Fei,Zhou, Li-Jin,Zheng, An-Qi,Miao, Chun-Bao,Yang, Hai-Tao

supporting information, p. 3153 - 3157 (2019/05/10)

A Cu(OAc)2-promoted cascade reaction of malonate-tetherd acyl oximes with indoles, indole-2-alcohols, or indole-2-carboxmides provides facile access to polysubstituted 3-pyrrolin-2-ones. The reaction features the generation of two adjacent elec

AMIDATION METHOD AND ESTERIFICATION METHOD USING SULFONIC ACID HALIDE

-

Paragraph 0038, (2017/01/17)

PROBLEM TO BE SOLVED: To provide a safe and economical method for rapidly synthesizing amides and esters in high yield. SOLUTION: There is provided a method for amidating an amine or a derivative thereof using a sulfonic acid halide, where a sulfonic acid halide is allowed to act as an activator on a carboxylic acid or a derivative thereof to synthesize an active ester, and the active ester is reacted with an amine or a derivative thereof as a nucleophile to amidate the amine or the derivative thereof to obtain a corresponding amide or a derivative thereof. In a similar manner, a sulfonic acid halide is allowed to act as an activator on a carboxylic acid or a derivative thereof to synthesize an active ester, and the active ester is reacted with an alcohol or a derivative thereof as a nucleophile to esterify the alcohol or the derivative thereof to obtain a corresponding ester or a derivative thereof.

Synthesis of heteroarylogous 1H-indole-3-carboxamidines via a three-component interrupted Ugi reaction

La Spisa, Fabio,Meneghetti, Fiorella,Pozzi, Beatrice,Tron, Gian Cesare

, p. 489 - 496 (2015/02/19)

A novel one-pot multicomponent synthesis of heteroarylogous 1H-indole-3-carboxamidines starting from readily available N-alkyl-N-(1H-indol-2-ylmethyl)amines, isocyanides, and carbonyl compounds is reported. The strategy exploits the ability of the indole nucleus to interrupt the classical Ugi reaction, by intercepting the nascent nitrilium ion.
