Check Digit Verification of cas no

The CAS Registry Mumber 1378387-81-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,3,8 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1378387-81:
(9*1)+(8*3)+(7*7)+(6*8)+(5*3)+(4*8)+(3*7)+(2*8)+(1*1)=215
215 % 10 = 5
So 1378387-81-5 is a valid CAS Registry Number.
