Check Digit Verification of cas no

The CAS Registry Mumber 21782-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,8 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21782-87:
(7*2)+(6*1)+(5*7)+(4*8)+(3*2)+(2*8)+(1*7)=116
116 % 10 = 6
So 21782-87-6 is a valid CAS Registry Number.
