Check Digit Verification of cas no

The CAS Registry Mumber 90261-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,6 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90261-67:
(7*9)+(6*0)+(5*2)+(4*6)+(3*1)+(2*6)+(1*7)=119
119 % 10 = 9
So 90261-67-9 is a valid CAS Registry Number.

RESEARCH ON UNSATURATED LACTONES. 91.* SELECTIVE OXIDATION OF THE BROMOETHYL GROUP IN SUBSTITUTED 2-BUTEN-4-OLIDES

Avetisyan, A. A.,Ovsepyan, V. V.,Tokmadzhyan, G. G.

, p. 594 - 598 (1984)

The selective oxidation of the bromomethyl group to a formyl group was realized by the direct action of dimethyl sulfoxide on 2-ethoxycarbonyl-3-bromomethyl-4,4-dialkyl(cycloalkyl)-2-buten-4-olides.
