Check Digit Verification of cas no
The CAS Registry Mumber 7452-51-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,5 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7452-51:
(6*7)+(5*4)+(4*5)+(3*2)+(2*5)+(1*1)=99
99 % 10 = 9
So 7452-51-9 is a valid CAS Registry Number.
