Check Digit Verification of cas no

The CAS Registry Mumber 70892-81-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,9 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70892-81:
(7*7)+(6*0)+(5*8)+(4*9)+(3*2)+(2*8)+(1*1)=148
148 % 10 = 8
So 70892-81-8 is a valid CAS Registry Number.
