1202539-33-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1202539-33-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,5,3 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1202539-33:
(9*1)+(8*2)+(7*0)+(6*2)+(5*5)+(4*3)+(3*9)+(2*3)+(1*3)=110
110 % 10 = 0
So 1202539-33-0 is a valid CAS Registry Number.

Applying lipase catalysis to access the enantiomers of dorzolamide intermediates
Turcu, Mihaela C.,Rantapaju, Maria,Kanerva, Liisa T.
, p. 5594 - 5600 (2009)
The kinetic resolution of three dorzolamide intermediates has been studied in the presence of Burkholderia cepacia li-pase in organic solvents. All the stereoisomers of 6-methyl-5,6-dihydro-4H-thieno[2,3-b]thiopyran-4-ol were prepared starting from the ra
