74399-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74399-43-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,9 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74399-43:
(7*7)+(6*4)+(5*3)+(4*9)+(3*9)+(2*4)+(1*3)=162
162 % 10 = 2
So 74399-43-2 is a valid CAS Registry Number.
