Check Digit Verification of cas no

The CAS Registry Mumber 81262-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,6 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81262-50:
(7*8)+(6*1)+(5*2)+(4*6)+(3*2)+(2*5)+(1*0)=112
112 % 10 = 2
So 81262-50-2 is a valid CAS Registry Number.
