52157-07-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52157-07-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 52157-07:
(7*5)+(6*2)+(5*1)+(4*5)+(3*7)+(2*0)+(1*7)=100
100 % 10 = 0
So 52157-07-0 is a valid CAS Registry Number.
