Check Digit Verification of cas no

The CAS Registry Mumber 102437-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,4,3 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 102437-04:
(8*1)+(7*0)+(6*2)+(5*4)+(4*3)+(3*7)+(2*0)+(1*4)=77
77 % 10 = 7
So 102437-04-7 is a valid CAS Registry Number.

General Syntheses of 6- and 7-Carbomethoxy-trans-1-heteradecalins and 6- and 7-Carbomethoxy-trans-2-heteradecalins

Hirsch, Jerry A.,Truc, Vu Chi

, p. 2218 - 2227 (2007/10/02)

Two routes to all of the title compounds in the oxa and aza series have been studied.The most general path, involving a cyclohexene oxide intermediate, was not successful becauase of difficulty in separating regioisomers.Allylation of 4-carbomethoxycyclohexanone (11) followed by reduction produced the required trans-disubstituted allyl alcohols, which were converted to all of the desired 6-carbomethoxy-trans-1-heteradecalins.The allyl ketones were subjected to a homologation-side chain contraction sequence to produce the 6-carbomethoxy-trans-2-heteradecalins.Allylation of 3-carbomethoxycyclohexanone (12) was not regioselective, but all four product isomers were characterized.The desired 5-carbomethoxy-2-allylcyclohexanone isomers (27 and 28) were converted to the 7-carbomethoxy-trans-decalins by similar series of reactions
