134840-33-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134840-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134840-33:
(8*1)+(7*3)+(6*4)+(5*8)+(4*4)+(3*0)+(2*3)+(1*3)=118
118 % 10 = 8
So 134840-33-8 is a valid CAS Registry Number.

Lipase-Catalyzed Enantioselective Esterification of 2-Methylalkanoic Acids
Engel, Karl-Heinz
, p. 165 - 168 (2007/10/02)
A preference for (S)-enantiomers has been observed in the course of the esterification of racemic 2-methylalkanoic acids catalyzed by lipase from Candida cylindracea in heptane.
