85121-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85121-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,2 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85121-73:
(7*8)+(6*5)+(5*1)+(4*2)+(3*1)+(2*7)+(1*3)=119
119 % 10 = 9
So 85121-73-9 is a valid CAS Registry Number.
