Check Digit Verification of cas no
The CAS Registry Mumber 142705-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,0 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142705-97:
(8*1)+(7*4)+(6*2)+(5*7)+(4*0)+(3*5)+(2*9)+(1*7)=123
123 % 10 = 3
So 142705-97-3 is a valid CAS Registry Number.

Efficient syntheses of (S)-4-hydroxy-2-pyrrolidinone derivatives
Kanno, Osamu,Miyauchi, Masao,Kawamoto, Isao
, p. 173 - 181 (2007/10/03)
Efficient syntheses of (S)-4-hydroxy-2-pyrrolidinone ((5)-2) and (R)4- acetylthio-2-pyrrolidinone (S), which are key intermediates of oral carbapenem CS-834, were studied. The most efficient route to (S)-2 from (S)- 3-hydroxybutyrolactone (8) was accomplished in high yield via (S)-N-allyl-3- (1-ethoxy)ethoxy-4-hydroxybutyramide (14).
