131222-93-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131222-93-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,2 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131222-93:
(8*1)+(7*3)+(6*1)+(5*2)+(4*2)+(3*2)+(2*9)+(1*3)=80
80 % 10 = 0
So 131222-93-0 is a valid CAS Registry Number.

Efficient synthesis of optically active cis-endo-2,3-dihydroxymethyl-5-norbornene monoacetate by lipase-catalyzed transesterification
Murata,Uchida,Achiwa
, p. 2610 - 2613 (2007/10/02)
Chiral cis-endo-2,3-dihydroxymethyl-5-norbornene monoacetate was produced by lipase-catalyzed asymmetric transesterification, and used to synthesize an optically active thromboxane A2 (TXA2) antagonist.
