725253-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 725253-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,5,2,5 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 725253-55:
(8*7)+(7*2)+(6*5)+(5*2)+(4*5)+(3*3)+(2*5)+(1*5)=154
154 % 10 = 4
So 725253-55-4 is a valid CAS Registry Number.
