Check Digit Verification of cas no

The CAS Registry Mumber 1219939-86-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,9,3 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1219939-86:
(9*1)+(8*2)+(7*1)+(6*9)+(5*9)+(4*3)+(3*9)+(2*8)+(1*6)=192
192 % 10 = 2
So 1219939-86-2 is a valid CAS Registry Number.
