Check Digit Verification of cas no
The CAS Registry Mumber 150937-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,9,3 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 150937-43:
(8*1)+(7*5)+(6*0)+(5*9)+(4*3)+(3*7)+(2*4)+(1*3)=132
132 % 10 = 2
So 150937-43-2 is a valid CAS Registry Number.

Process for the preparation of brinzolamide and intermediates thereof
-
Page/Page column 11, (2008/12/04)
Preparation process of brinzolamide of formula (I) comprising the protection of the secondary amine of their non sulfonamide substituted precursor; the chlorosulfonation and the subsequent amination with ammonia of the obtained intermediate; and, finally, the deprotection of the obtained sulfonamide by acid hydrolysis. The process allows to obtain brinzolamide at a industrial scale by using milder reaction conditions and with a high yield at reduced costs. Some new intermediates are used in this process.
