Check Digit Verification of cas no

The CAS Registry Mumber 78381-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,8 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78381-18:
(7*7)+(6*8)+(5*3)+(4*8)+(3*1)+(2*1)+(1*8)=157
157 % 10 = 7
So 78381-18-7 is a valid CAS Registry Number.
