113542-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113542-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,4 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 113542-17:
(8*1)+(7*1)+(6*3)+(5*5)+(4*4)+(3*2)+(2*1)+(1*7)=89
89 % 10 = 9
So 113542-17-9 is a valid CAS Registry Number.

Iminium Ions as Initiators and Allylsilanes as Terminators in Polyolefin Cyclizations: Total Synthesis of (+/-)-Yohimbone via A Vinylogous Aminomethano Desilylation
Grieco, Paul A.,Fobare, William F.
, p. 185 - 186 (2007/10/02)
A syntyheses of (+/-)-yohimbone has been realized via a concerted iminium ion-induced polyolefin cyclization terminated by an allylsilane.
