Check Digit Verification of cas no

The CAS Registry Mumber 216697-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,6,9 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 216697-71:
(8*2)+(7*1)+(6*6)+(5*6)+(4*9)+(3*7)+(2*7)+(1*1)=161
161 % 10 = 1
So 216697-71-1 is a valid CAS Registry Number.
