80523-29-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80523-29-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,2 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 80523-29:
(7*8)+(6*0)+(5*5)+(4*2)+(3*3)+(2*2)+(1*9)=111
111 % 10 = 1
So 80523-29-1 is a valid CAS Registry Number.
