80989-69-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80989-69-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 80989-69:
(7*8)+(6*0)+(5*9)+(4*8)+(3*9)+(2*6)+(1*9)=181
181 % 10 = 1
So 80989-69-1 is a valid CAS Registry Number.
