Check Digit Verification of cas no

The CAS Registry Mumber 197703-70-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,0 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 197703-70:
(8*1)+(7*9)+(6*7)+(5*7)+(4*0)+(3*3)+(2*7)+(1*0)=171
171 % 10 = 1
So 197703-70-1 is a valid CAS Registry Number.
