74508-94-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74508-94-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,0 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74508-94:
(7*7)+(6*4)+(5*5)+(4*0)+(3*8)+(2*9)+(1*4)=144
144 % 10 = 4
So 74508-94-4 is a valid CAS Registry Number.
