Check Digit Verification of cas no

The CAS Registry Mumber 1220572-67-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,5,7 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1220572-67:
(9*1)+(8*2)+(7*2)+(6*0)+(5*5)+(4*7)+(3*2)+(2*6)+(1*7)=117
117 % 10 = 7
So 1220572-67-7 is a valid CAS Registry Number.

Design of a versatile multicomponent reaction leading to 2-amino-5-ketoaryl pyrroles

Wang, Kan,Doemling, Alexander

experimental part, p. 277 - 283 (2010/12/19)

The design of an unprecedented multicomponent reaction to and synthesis of 2-amino-5-ketoaryl pyrroles are described. The compounds (14 examples) can be synthesized by reacting aminoacetophenone sulfonamides, (hetero)aromatic aldehydes, and malonodinitrile or cyanoacetic acid derivatives in one-pot manner. Pharmacophore features and potential applications of this new scaffold are discussed.
