Check Digit Verification of cas no

The CAS Registry Mumber 1142425-59-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,2,4,2 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1142425-59:
(9*1)+(8*1)+(7*4)+(6*2)+(5*4)+(4*2)+(3*5)+(2*5)+(1*9)=119
119 % 10 = 9
So 1142425-59-9 is a valid CAS Registry Number.

Synthesis of 2-(4′-R-benzylidene)-4-aza-1,3-indanediones and investigation of isomerization around the exocyclic double bond

Petrova,Liepinsh,Pastors,Fleisher,Kampars

, p. 820 - 827 (2008)

2-Benzylidene-4-aza-1,3-indanediones have been synthesized and their structures have been investigated by NMR spectroscopy and quantum chemistry in the AM1 approximation. It was established that rotation about the exocyclic C(2)=C(10) formal double bond o
