937733-22-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 937733-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,7,7,3 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 937733-22:
(8*9)+(7*3)+(6*7)+(5*7)+(4*3)+(3*3)+(2*2)+(1*2)=197
197 % 10 = 7
So 937733-22-7 is a valid CAS Registry Number.

supporting information, p. 160 - 169 (2018/12/04)

An intramolecular oxidative amidation of varied α-[(β-dimethylamino)propenoyl]-alkylamides catalyzed by copper(II) bromide in the presence of PIFA and TFA has been described. This process features mild reaction conditions, simple execution, good yields, h

Intramolecular aza-anti-Michael addition of an amide anion to enones: A regiospecific approach to tetramic acid derivatives

Bi, Xihe,Zhang, Jingping,Liu, Qun,Tan, Jing,Li, Bing

, p. 2301 - 2306 (2008/09/19)

A novel intramolecular aza-anti-Michael addition was disclosed in the one-pot reactions between 3-oxobutanamides and aryl (heteroaryl) aldehydes under basic conditions, in which amide anions regiospecifically attacked the ct-carbon of an enone fragment, p
