Check Digit Verification of cas no

The CAS Registry Mumber 1337993-48-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,9,9 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1337993-48:
(9*1)+(8*3)+(7*3)+(6*7)+(5*9)+(4*9)+(3*3)+(2*4)+(1*8)=202
202 % 10 = 2
So 1337993-48-2 is a valid CAS Registry Number.
