180524-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 180524-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,5,2 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 180524-20:
(8*1)+(7*8)+(6*0)+(5*5)+(4*2)+(3*4)+(2*2)+(1*0)=113
113 % 10 = 3
So 180524-20-3 is a valid CAS Registry Number.
