Check Digit Verification of cas no
The CAS Registry Mumber 123217-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,1 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123217-82:
(8*1)+(7*2)+(6*3)+(5*2)+(4*1)+(3*7)+(2*8)+(1*2)=93
93 % 10 = 3
So 123217-82-3 is a valid CAS Registry Number.

Selective Wittig Reactions for the Synthesis of Variously Substituted 2-Vinylindoles
Eitel, Manfred,Pindur, Ulf
, p. 364 - 367 (2007/10/02)
Three selective variants of the Wittig reaction for the syntheses of 2-vinylindoles are described.The reactions are relatively easy to perform, exhibit E-selectivity, and are characterized by a good flexibility with regard to the functional groups present in the vinyl moiety.
