357439-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 357439-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,4,3 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 357439-45:
(8*3)+(7*5)+(6*7)+(5*4)+(4*3)+(3*9)+(2*4)+(1*5)=173
173 % 10 = 3
So 357439-45-3 is a valid CAS Registry Number.
