80899-91-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80899-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,9 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80899-91:
(7*8)+(6*0)+(5*8)+(4*9)+(3*9)+(2*9)+(1*1)=178
178 % 10 = 8
So 80899-91-8 is a valid CAS Registry Number.
