74213-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74213-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,1 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74213-91:
(7*7)+(6*4)+(5*2)+(4*1)+(3*3)+(2*9)+(1*1)=115
115 % 10 = 5
So 74213-91-5 is a valid CAS Registry Number.

Kakinuma, Katsumi,Otake, Noboru,Yonehara, Hiroshi
, p. 167 - 168 (2007/10/02)
A stereocpecific synthesis of acetyl-L-valyl-detoxininolactone has been performed and the absolute stereochemistry of detoxinine has been revised to (2S,3R,1'S)-2-(2'-carboxy-1'-hydroxyethyl)-3-hydroxypyrrolidine.
