The CAS Registry Mumber 97250-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,5 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97250-90:
(7*9)+(6*7)+(5*2)+(4*5)+(3*0)+(2*9)+(1*0)=153
153 % 10 = 3
So 97250-90-3 is a valid CAS Registry Number.

A CONVENIENT METHOD FOR GENERATION OF TIN(II) THIOESTER ENOLATE AND ITS REACTION WITH ALDEHYDE

Mukaiyama, Teruaki,Yamasaki, Noritsugu,Stevens, Rodney W.,Murakami, Masahiro

, p. 213 - 216 (2007/10/02)

Tin(II) enolates of thioesters are conveniently generated by the addition of stannous thiolates to ketenes.The tin(II) enolates thus formed react with aldehydes to afford the corresponding β-hydroxythioesters in a syn-selective manner.And this method is applied to an enantioselective formation of β-hydroxythioesters by the use of a chiral diamine as ligand.
