Check Digit Verification of cas no
The CAS Registry Mumber 7227-45-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,2 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7227-45:
(6*7)+(5*2)+(4*2)+(3*7)+(2*4)+(1*5)=94
94 % 10 = 4
So 7227-45-4 is a valid CAS Registry Number.
