Check Digit Verification of cas no

The CAS Registry Mumber 76681-84-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,8 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 76681-84:
(7*7)+(6*6)+(5*6)+(4*8)+(3*1)+(2*8)+(1*4)=170
170 % 10 = 0
So 76681-84-0 is a valid CAS Registry Number.

A Novel Oxamide Rearrangement

Peet, Norton P.,Sunder, Shyam,Barbuch, Robert J.

, p. 1513 - 1518 (2007/10/02)

An efficient, base-induced rearrangement of 2-benzoic acid methyl ester (7a) to the isomeric 2-benzoic acid methyl ester (27a) is described.This novel rearrangement must proceed through a spiro intermediate wherein benzoate is acting as a Michael receptor.When 2-benzoic acid methyl ester (28) - an oxamide which would produce a degenerate spiro intermediate - was subjected to rearrangement conditions, the product obtained was 1,3-dimethyl-2,4-(1H,3H)quinazolinedione (29).This latter transformation may have proceeded via a benzodiazepinetrione intermediate.
