Check Digit Verification of cas no

The CAS Registry Mumber 139658-00-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,5 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139658-00:
(8*1)+(7*3)+(6*9)+(5*6)+(4*5)+(3*8)+(2*0)+(1*0)=157
157 % 10 = 7
So 139658-00-7 is a valid CAS Registry Number.
