1439357-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1439357-01-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,3,5 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1439357-01:
(9*1)+(8*4)+(7*3)+(6*9)+(5*3)+(4*5)+(3*7)+(2*0)+(1*1)=173
173 % 10 = 3
So 1439357-01-3 is a valid CAS Registry Number.
