Check Digit Verification of cas no
The CAS Registry Mumber 143731-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,3 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143731-32:
(8*1)+(7*4)+(6*3)+(5*7)+(4*3)+(3*1)+(2*3)+(1*2)=112
112 % 10 = 2
So 143731-32-2 is a valid CAS Registry Number.

Amine assisted enzymatic esterification of 1,2-diol monotosylates
Boaz,Zimmerman
, p. 153 - 156 (2007/10/02)
The enzymatic esterification of 1,2-diol monotosylates in organic solvent under standard conditions often fails to achieve the desired 50% conversion due to enzyme inactivation by acidic contaminants. The inclusion of an amine affords rapid conversion to
