Check Digit Verification of cas no

The CAS Registry Mumber 121881-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,8 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121881-34:
(8*1)+(7*2)+(6*1)+(5*8)+(4*8)+(3*1)+(2*3)+(1*4)=113
113 % 10 = 3
So 121881-34-3 is a valid CAS Registry Number.

A New Method for C-C Coupling of Terminal Alkenes via a Sulphonylation-Alkylation-Desulphinylation Sequence: Synthesis of E- and Z-α-Bisabolenes

Baldwin, Jack E.,Adlington, Robert M.,Ichikawa, Yoshiyasu,Kneale, Christopher J.

, p. 702 - 704 (2007/10/02)

A new method for regiospecific C-C coupling of terminal alkenes based on a sulphonylation-alkylation-desulphinylation process, mediated through allylic sulphinic acids, and its application to the conversion of limonene into E- and Z-α-bisabolenes, are described.
