89000-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89000-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,0 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89000-73:
(7*8)+(6*9)+(5*0)+(4*0)+(3*0)+(2*7)+(1*3)=127
127 % 10 = 7
So 89000-73-7 is a valid CAS Registry Number.
