Check Digit Verification of cas no
The CAS Registry Mumber 7497-72-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7497-72:
(6*7)+(5*4)+(4*9)+(3*7)+(2*7)+(1*2)=135
135 % 10 = 5
So 7497-72-5 is a valid CAS Registry Number.
