Check Digit Verification of cas no

The CAS Registry Mumber 136831-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,3 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136831-17:
(8*1)+(7*3)+(6*6)+(5*8)+(4*3)+(3*1)+(2*1)+(1*7)=129
129 % 10 = 9
So 136831-17-9 is a valid CAS Registry Number.

Efficient synthesis of 3-hydroxymethylated cis- and trans-cyclobutane β-amino acids using an intramolecular photocycloaddition strategy

Mondière, Aurélie,Peng, Runhui,Remuson, Roland,Aitken, David J.

, p. 1088 - 1093 (2008)

Uracil bearing a tethered allyl alcohol appendage at N1 undergoes a [2+2] photocycloaddition reaction to provide a single tricyclic adduct in high yield. This compound is transformed in one step into a cis-cyclobutane β-amino acid bearing a 3-hydroxymethyl group. Through appropriate functionalization and epimerization, the trans isomer is obtained therefrom in only three further steps.
