Check Digit Verification of cas no

The CAS Registry Mumber 971-84-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,7 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 971-84:
(5*9)+(4*7)+(3*1)+(2*8)+(1*4)=96
96 % 10 = 6
So 971-84-6 is a valid CAS Registry Number.
