Check Digit Verification of cas no

The CAS Registry Mumber 1241680-48-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,6,8 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1241680-48:
(9*1)+(8*2)+(7*4)+(6*1)+(5*6)+(4*8)+(3*0)+(2*4)+(1*8)=137
137 % 10 = 7
So 1241680-48-7 is a valid CAS Registry Number.
