Check Digit Verification of cas no

The CAS Registry Mumber 4851-70-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,5 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4851-70:
(6*4)+(5*8)+(4*5)+(3*1)+(2*7)+(1*0)=101
101 % 10 = 1
So 4851-70-1 is a valid CAS Registry Number.
