Check Digit Verification of cas no
The CAS Registry Mumber 421-95-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 421-95:
(5*4)+(4*2)+(3*1)+(2*9)+(1*5)=54
54 % 10 = 4
So 421-95-4 is a valid CAS Registry Number.
