Check Digit Verification of cas no

The CAS Registry Mumber 81836-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,3 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81836-90:
(7*8)+(6*1)+(5*8)+(4*3)+(3*6)+(2*9)+(1*0)=150
150 % 10 = 0
So 81836-90-0 is a valid CAS Registry Number.
