Check Digit Verification of cas no
The CAS Registry Mumber 2447-72-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,4 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2447-72:
(6*2)+(5*4)+(4*4)+(3*7)+(2*7)+(1*2)=85
85 % 10 = 5
So 2447-72-5 is a valid CAS Registry Number.
