Check Digit Verification of cas no

The CAS Registry Mumber 133295-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,9 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133295-83:
(8*1)+(7*3)+(6*3)+(5*2)+(4*9)+(3*5)+(2*8)+(1*3)=127
127 % 10 = 7
So 133295-83-7 is a valid CAS Registry Number.

Angular Hydroxymethylation of Functionalized Decalin Systems

Chan, T. H.,Schwerdtfeger, A. E.

, p. 3294 - 3298 (2007/10/02)

Functionalized β-dicarbonyl bicyclic compounds 5 and 17 were hydroxymethylated at the angular position as the (benzyloxy)methoxy derivatives with diisopropylethylamine (DIPEA) and benzyl chloromethyl ether in the presence of paraformaldehyde.The stereochemistry of cis-8a-methyl>-3-(phenylthio)-4a,5,6,8a-tetrahydronaphthalene-1,8(4H,7H)-dione (12) was confirmed by X-ray analysis of the ethylene ketal 16.
