Check Digit Verification of cas no
The CAS Registry Mumber 85287-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,8 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85287-89:
(7*8)+(6*5)+(5*2)+(4*8)+(3*7)+(2*8)+(1*9)=174
174 % 10 = 4
So 85287-89-4 is a valid CAS Registry Number.
