157523-11-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157523-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,2 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157523-11:
(8*1)+(7*5)+(6*7)+(5*5)+(4*2)+(3*3)+(2*1)+(1*1)=130
130 % 10 = 0
So 157523-11-0 is a valid CAS Registry Number.
