Check Digit Verification of cas no

The CAS Registry Mumber 21790-68-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,9 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21790-68:
(7*2)+(6*1)+(5*7)+(4*9)+(3*0)+(2*6)+(1*8)=111
111 % 10 = 1
So 21790-68-1 is a valid CAS Registry Number.
