191603-97-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191603-97-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,6,0 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 191603-97:
(8*1)+(7*9)+(6*1)+(5*6)+(4*0)+(3*3)+(2*9)+(1*7)=141
141 % 10 = 1
So 191603-97-1 is a valid CAS Registry Number.

Total Synthesis of (+/-)-Cylindricines A and B
Fields, Julie,Heathcock, Clayton H.
, p. 8263 - 8266 (2007/10/03)
Cylindricine A (1) and cylindricine B (2) have been aynthesized in 11 steps and 19 percent overall yield. The key reaction involves the addition of an organocopper species to a bicyclic vinylogous amide, which provides complete stereocontrol over the installation of the hexyl side chain.
