57444-13-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57444-13-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,4 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57444-13:
(7*5)+(6*7)+(5*4)+(4*4)+(3*4)+(2*1)+(1*3)=130
130 % 10 = 0
So 57444-13-0 is a valid CAS Registry Number.
