Check Digit Verification of cas no

The CAS Registry Mumber 1694-08-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1694-08:
(6*1)+(5*6)+(4*9)+(3*4)+(2*0)+(1*8)=92
92 % 10 = 2
So 1694-08-2 is a valid CAS Registry Number.
