Check Digit Verification of cas no
The CAS Registry Mumber 188407-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,4,0 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 188407-77:
(8*1)+(7*8)+(6*8)+(5*4)+(4*0)+(3*7)+(2*7)+(1*7)=174
174 % 10 = 4
So 188407-77-4 is a valid CAS Registry Number.

Pig liver esterase catalyzed hydrolysis of dimethyl and diethyl 2-methyl-2-(o-nitrophenoxy)malonates
Breznik, Matej,Kikelj, Danijel
, p. 425 - 434 (1997)
Pig liver esterase (PLE) catalyzed hydrolysis of dimethyl and diethyl 2-methyl-2-(o-nitrophenoxy)malonates affords (R)-monoethyl/monomethyl 2-methyl-2-(o-nitrophenoxy)malonates in moderate to good enantiomeric excesses (69-81%). These data indicate that t
