Check Digit Verification of cas no
The CAS Registry Mumber 169396-08-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,3,9 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 169396-08:
(8*1)+(7*6)+(6*9)+(5*3)+(4*9)+(3*6)+(2*0)+(1*8)=181
181 % 10 = 1
So 169396-08-1 is a valid CAS Registry Number.

Asymmetric functionalization of chromium carbene-derived optically active 4,4-disubstituted butenolides
Reed,Hegedus
, p. 3787 - 3794 (2007/10/02)
Optically active 4,4-disubstituted butenolides were readily prepared by photolysis of chromium alkoxycarbene complexes with optically active ene carbamates, followed by Baeyer-Villiger oxidation/oxazolidinone elimination. These butenolides underwent clean
