Check Digit Verification of cas no

The CAS Registry Mumber 6271-88-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,7 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6271-88:
(6*6)+(5*2)+(4*7)+(3*1)+(2*8)+(1*8)=101
101 % 10 = 1
So 6271-88-1 is a valid CAS Registry Number.
