The CAS Registry Mumber 6421-85-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6421-85:
(6*6)+(5*4)+(4*2)+(3*1)+(2*8)+(1*5)=88
88 % 10 = 8
So 6421-85-8 is a valid CAS Registry Number.
