Check Digit Verification of cas no

The CAS Registry Mumber 20694-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,9 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20694-33:
(7*2)+(6*0)+(5*6)+(4*9)+(3*4)+(2*3)+(1*3)=101
101 % 10 = 1
So 20694-33-1 is a valid CAS Registry Number.
