Check Digit Verification of cas no

The CAS Registry Mumber 168542-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,5,4 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 168542-76:
(8*1)+(7*6)+(6*8)+(5*5)+(4*4)+(3*2)+(2*7)+(1*6)=165
165 % 10 = 5
So 168542-76-5 is a valid CAS Registry Number.

, (2008/06/13)

A novel compound represented by the formula: STR1 wherein Ring A and Ring B respectively stands for an optionally substituted homo- or hetero-cyclic ring, and at least one of them stands for an optionally substituted heterocyclic ring stand; Ring C stands for an optionally substituted benzene ring; R stands for a hydrogen atom or an optionally substituted hydrocarbon residue; one of X and Y stands for --NR1 -- (R1 stands for a hydrogen atom or an optionally substituted hydrocarbon residue) or --O--, and the other stands for--CO-- or --CS--, or one of them stands for --N= and the other stands for =CR2 -- (R2 stands for a hydrogen atom, a halogen atom, an optionally substituted hydrocarbon residue, an optionally substituted amino group or an optionally substituted hydroxyl group); n denotes 1 or 2 or salts thereof which have an excellent tachykinin receptor antagonistic action and inhibitory action on plasma extravasation.
