Check Digit Verification of cas no

The CAS Registry Mumber 1202520-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,5,2 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1202520-87:
(9*1)+(8*2)+(7*0)+(6*2)+(5*5)+(4*2)+(3*0)+(2*8)+(1*7)=93
93 % 10 = 3
So 1202520-87-3 is a valid CAS Registry Number.

supporting information; experimental part, p. 36 - 39 (2010/03/04)

Chemical Equation Presented An efficient synthesis of the C1-C17 western unit of narasin was achieved from (S)-Roche ester. Highlights in our synthesis include the successful exploitation of three stereoselective sequences of Lewis acid mediated reaction followed by free-radical-based hydrogen transfer.
