The CAS Registry Mumber 83121-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,2 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83121-16:
(7*8)+(6*3)+(5*1)+(4*2)+(3*1)+(2*1)+(1*6)=98
98 % 10 = 8
