Check Digit Verification of cas no

The CAS Registry Mumber 1204211-93-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,2,1 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1204211-93:
(9*1)+(8*2)+(7*0)+(6*4)+(5*2)+(4*1)+(3*1)+(2*9)+(1*3)=87
87 % 10 = 7
So 1204211-93-7 is a valid CAS Registry Number.

, p. 6461 - 6465 (2021/08/23)

A novel [2 + 1 + 3] cyclization reaction for the synthesis of 2-aryl-4-quinolinecarboxylates from aryl methyl ketones, arylamines, and 1,3-dicarbonyl compounds has been established. This metal-free process achieved the C-C bond cleavage of 1,3-dicarbonyl compounds directly as a single-carbon synthon. The reaction is highly efficient and has good substrate compatibility while operating under mild conditions. This method has good practicability and successfully realized the synthesis of bioactive molecules.
