Check Digit Verification of cas no

The CAS Registry Mumber 1413547-40-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,3,5,4 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1413547-40:
(9*1)+(8*4)+(7*1)+(6*3)+(5*5)+(4*4)+(3*7)+(2*4)+(1*0)=136
136 % 10 = 6
So 1413547-40-6 is a valid CAS Registry Number.

A synthetic method to access symmetric and non-symmetric 2-(N,N'-disubstituted)guanidinebenzothiazoles

Cruz, Alejandro,Padilla-Martinez, Itzia I.,Garcia-Baez, Efren V.

, p. 10178 - 10191,14 (2020/09/09)

Symmetric and non-symmetric 2-(N-H, N-methyl, N-ethylenyl and N-aryl)guanidinebenzothiazoles were synthesized from the reaction of ammonia, methylamine, pyrrolidine and aniline with dimethyl benzo[d]thiazol-2-yl- carbonodithioimidate (5) as intermediate. The products were characterized by 1H-, 13C-NMR spectroscopy and three of them by X-ray diffraction analysis. HN-phenyl protons formed intramolecular hydrogen bonds that assist the stereochemistry of the second substituent, whereas the HN-alkyl protons were involved in intermolecular hydrogen bonding.
