Check Digit Verification of cas no
The CAS Registry Mumber 1197349-22-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,3,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1197349-22:
(9*1)+(8*1)+(7*9)+(6*7)+(5*3)+(4*4)+(3*9)+(2*2)+(1*2)=186
186 % 10 = 6
So 1197349-22-6 is a valid CAS Registry Number.

Synthetic studies towards iriomoteolide-1a: Construction of the C13-C23 fragment
Ye, Zhengqing,Deng, Lisheng,Qian, Shan,Zhao, Gang
, p. 2469 - 2472 (2009)
A stereoselective synthesis of the C13-C23 segment of iriomoteolide-1a was achieved using, as key steps, a highly stereocontrolled crotylation to build the stereocenters at C18 and C19 and a Julia-Kocienski olefination to establish the C15-C16 E-olefin mo
