Uses
N-[(4S,6S)-2-(Aminosulfonyl)-5,6-dihydro-6-methyl-7,7-dioxido-4H-thieno[2,3-b]thiopyran-4-yl]acetamide is used as a reagent in the synthesis of MK-0507, a topically-active carbonic anhydrase inhibitor.
Check Digit Verification of cas no
The CAS Registry Mumber 147200-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,2,0 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 147200-03:
(8*1)+(7*4)+(6*7)+(5*2)+(4*0)+(3*0)+(2*0)+(1*3)=91
91 % 10 = 1
So 147200-03-1 is a valid CAS Registry Number.
