Check Digit Verification of cas no

The CAS Registry Mumber 113309-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,0 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113309-41:
(8*1)+(7*1)+(6*3)+(5*3)+(4*0)+(3*9)+(2*4)+(1*1)=84
84 % 10 = 4
So 113309-41-4 is a valid CAS Registry Number.

SmI2-INDUCED HIGHLY REGIOSELECTIVE REDUCTION OF α,β-EPOXY ESTERS AND γ,δ-EPOXY-α,β-UNSATURATED ESTERS. AN EFFICIENT ROUTE TO OPTICALLY ACTIVE β-HYDROXY AND δ-HYDROXY ESTERS

Otsubo, Kenji,Inanaga, Junji,Yamaguchi, Masaru

, p. 4437 - 4440 (2007/10/02)

α,β-Epoxy esters were rapidly reduced at room temperature to yield β-hydroxy esters with retention of the configurations at the β-carbon atoms by using SmI2-THF-HMPA system in the presence of N,N-dimethylaminoethanol (DMAE).The conditions were successfully applied to the synthesis of vinylogous δ-hydroxy esters.
