Check Digit Verification of cas no

The CAS Registry Mumber 934630-44-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,6,3 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 934630-44:
(8*9)+(7*3)+(6*4)+(5*6)+(4*3)+(3*0)+(2*4)+(1*4)=171
171 % 10 = 1
So 934630-44-1 is a valid CAS Registry Number.

An efficient DABCO-catalyzed Ireland-Claisen rearrangement of allylic acrylates

Li, Yunxia,Wang, Quanrui,Goeke, Andreas,Fráter, Georg

, p. 288 - 292 (2007)

A novel DABCO-catalyzed Ireland-Claisen [3,3]-rearrangement of allylic acrylates to give α-methylene-γ,δ-unsaturated carboxylic acids in the presence of an excess of TMSCl and DBU in refluxing acetonitrile was developed. The protocol provides an easy entry to α-methylene-γ, δ-unsaturated carboxylic acids from allylic alcohols in good yields. Georg Thieme Verlag Stuttgart.
