725253-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 725253-50-9 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 0 respectively.
Calculate Digit Verification of CAS Registry Number 725253-50:
(8*7)+(7*2)+(6*5)+(5*2)+(4*5)+(3*3)+(2*5)+(1*0)=149
149 % 10 = 9
So 725253-50-9 is a valid CAS Registry Number.
