Check Digit Verification of cas no

The CAS Registry Mumber 140710-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,7,1 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140710-20:
(8*1)+(7*4)+(6*0)+(5*7)+(4*1)+(3*0)+(2*2)+(1*0)=79
79 % 10 = 9
So 140710-20-9 is a valid CAS Registry Number.

Regio-, stereo-, and enantioselective synthesis of cyclobutanols by means of the photoaddition of 1,3-dioxin-4-ones and lipase-catalyzed acetylation

Sato,Ohuchi,Abe,Kaneko

, p. 313 - 328 (2007/10/02)

Homochiral cis-2-hydroxymethylcyclobutanols, their all cis 3-methyl, and 4-hydroxymethyl derivatives were synthesized from 1,3-dioxin-4-ones via cyclobutane ring formation by [2+2]photocycloaddition, dioxanone ring cleavage, and reduction, followed by lip
