Check Digit Verification of cas no

The CAS Registry Mumber 3642-16-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,4 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3642-16:
(6*3)+(5*6)+(4*4)+(3*2)+(2*1)+(1*6)=78
78 % 10 = 8
So 3642-16-8 is a valid CAS Registry Number.
