23180-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23180-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,8 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 23180-28:
(7*2)+(6*3)+(5*1)+(4*8)+(3*0)+(2*2)+(1*8)=81
81 % 10 = 1
So 23180-28-1 is a valid CAS Registry Number.
