Check Digit Verification of cas no

The CAS Registry Mumber 51848-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,4 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 51848-99:
(7*5)+(6*1)+(5*8)+(4*4)+(3*8)+(2*9)+(1*9)=148
148 % 10 = 8
So 51848-99-8 is a valid CAS Registry Number.
