Check Digit Verification of cas no

The CAS Registry Mumber 29309-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,3,0 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 29309-01:
(7*2)+(6*9)+(5*3)+(4*0)+(3*9)+(2*0)+(1*1)=111
111 % 10 = 1
So 29309-01-1 is a valid CAS Registry Number.
