Check Digit Verification of cas no

The CAS Registry Mumber 138557-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,5 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138557-91:
(8*1)+(7*3)+(6*8)+(5*5)+(4*5)+(3*7)+(2*9)+(1*1)=162
162 % 10 = 2
So 138557-91-2 is a valid CAS Registry Number.

-

, (2008/06/13)

Pyrimidinedione derivatives of the formula: STR1 wherein R1 and R2 is so linked with each other as to make an alkylene chain and thus form a heterocyclic structure, A, R3, R4, X1, X2 and X3 are substituents, respectively, and n is 2 or 3 have a basic backbone in which a phenyl group part and a pyrimidinedione part are linked by a structure comprising an alkyl chain and a heterocyclic ring having two nitrogen atoms. These compounds are useful for a medical treatment of cardiac arrhythmias.
