Check Digit Verification of cas no

The CAS Registry Mumber 1309883-49-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,8 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1309883-49:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*8)+(3*3)+(2*4)+(1*9)=185
185 % 10 = 5
So 1309883-49-5 is a valid CAS Registry Number.
