Check Digit Verification of cas no

The CAS Registry Mumber 693778-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,3,7,7 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 693778-32:
(8*6)+(7*9)+(6*3)+(5*7)+(4*7)+(3*8)+(2*3)+(1*2)=224
224 % 10 = 4
So 693778-32-4 is a valid CAS Registry Number.
