Check Digit Verification of cas no

The CAS Registry Mumber 289622-50-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,6,2 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 289622-50:
(8*2)+(7*8)+(6*9)+(5*6)+(4*2)+(3*2)+(2*5)+(1*0)=180
180 % 10 = 0
So 289622-50-0 is a valid CAS Registry Number.

Stereochemistry and total synthesis of janolusimide, a tripeptide marine toxin

Giordano, Assunta,Della Monica, Carmela,Landi, Francesco,Spinella, Aldo,Sodano, Guido

, p. 3979 - 3982 (2007/10/03)

The stereochemistry of janolusimide, a lipophilic tripeptide marine toxin, has been fully elucidated by stereoselective synthesis of the lactam component (5S)-3,3'-dimethyl-5-isopropylpyrrolidin-2,4-dione. The peptide was then synthesized in 13 steps and in 0.8% total yield. (C) 2000 Elsevier Science Ltd.
