Check Digit Verification of cas no

The CAS Registry Mumber 620970-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,9,7 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 620970-72:
(8*6)+(7*2)+(6*0)+(5*9)+(4*7)+(3*0)+(2*7)+(1*2)=151
151 % 10 = 1
So 620970-72-1 is a valid CAS Registry Number.
