Check Digit Verification of cas no

The CAS Registry Mumber 947-86-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 947-86:
(5*9)+(4*4)+(3*7)+(2*8)+(1*6)=104
104 % 10 = 4
So 947-86-4 is a valid CAS Registry Number.
