252575-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252575-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,5,7 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 252575-70:
(8*2)+(7*5)+(6*2)+(5*5)+(4*7)+(3*5)+(2*7)+(1*0)=145
145 % 10 = 5
So 252575-70-5 is a valid CAS Registry Number.
