Check Digit Verification of cas no
The CAS Registry Mumber 607-56-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 607-56:
(5*6)+(4*0)+(3*7)+(2*5)+(1*6)=67
67 % 10 = 7
So 607-56-7 is a valid CAS Registry Number.

Synthesis of heterocyclic systems by the reaction of zwitterionic compounds with isocyanates and thiophosgene
Zaleska, Barbara,Karelus, Marcin
, p. 1831 - 1834 (2007/10/03)
The reaction of various isocyanates or thiophosgene with zwitterionic pyrimidinylium and 1,3-diazepinylium derivatives has led to the formation of unusually substituted [1,3]oxazolo[3,4-a]pyrimidines and novel heterocyclic system such as [1,3]oxazolo[3,4-
