Check Digit Verification of cas no

The CAS Registry Mumber 866722-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,6,7,2 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 866722-19:
(8*8)+(7*6)+(6*6)+(5*7)+(4*2)+(3*2)+(2*1)+(1*9)=202
202 % 10 = 2
So 866722-19-2 is a valid CAS Registry Number.
