Check Digit Verification of cas no

The CAS Registry Mumber 136521-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,2 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136521-19:
(8*1)+(7*3)+(6*6)+(5*5)+(4*2)+(3*1)+(2*1)+(1*9)=112
112 % 10 = 2
So 136521-19-2 is a valid CAS Registry Number.
