Check Digit Verification of cas no
The CAS Registry Mumber 272773-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,2,7,7 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 272773-62:
(8*2)+(7*7)+(6*2)+(5*7)+(4*7)+(3*3)+(2*6)+(1*2)=163
163 % 10 = 3
So 272773-62-3 is a valid CAS Registry Number.

The chemistry of vicinal tricarbonyls. Formation of oxomalondiamides
Wasserman, Harry H.,Lee, Kieseung,Xia, Mingde
, p. 2511 - 2514 (2000)
Oxomalondiamides and related systems are readily formed from derivatives of oxalic acid monoamides. The monoamides are converted to labile triacyl nitriles through cyano ylide intermediates for further coupling with amines and other nucleophiles. (C) 2000
