33647-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33647-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,4 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33647-74:
(7*3)+(6*3)+(5*6)+(4*4)+(3*7)+(2*7)+(1*4)=124
124 % 10 = 4
So 33647-74-4 is a valid CAS Registry Number.

Lipase-mediated preparation of enantiopure isolevoglucosenone
Kadota,ElAzab,Taniguchi,Ogasawara
, p. 1372 - 1374 (2007/10/03)
A route to enantiopure isolevoglucosenone, a regioisomer of levoglucosenone and a potential chiral building block, has been developed by employing lipase-mediated kinetic resolution as the key step.
