Check Digit Verification of cas no
The CAS Registry Mumber 74455-30-4 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 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74455-30:
(7*7)+(6*4)+(5*4)+(4*5)+(3*5)+(2*3)+(1*0)=134
134 % 10 = 4
So 74455-30-4 is a valid CAS Registry Number.
