80916-81-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80916-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,1 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80916-81:
(7*8)+(6*0)+(5*9)+(4*1)+(3*6)+(2*8)+(1*1)=140
140 % 10 = 0
So 80916-81-0 is a valid CAS Registry Number.
