StainCheck Digit Verification of cas no
The CAS Registry Mumber 86543-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,4 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.Calculate Digit Verification of CAS Registry Number 86543-85:
(7*8)+(6*6)+(5*5)+(4*4)+(3*3)+(2*8)+(1*5)=163
163 % 10 = 3
So 86543-85-3 is a valid CAS Registry Number.
