Check Digit Verification of cas no
The CAS Registry Mumber 74458-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,5 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74458-05:
(7*7)+(6*4)+(5*4)+(4*5)+(3*8)+(2*0)+(1*5)=142
142 % 10 = 2
So 74458-05-2 is a valid CAS Registry Number.
