80986-03-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80986-03-4 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 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80986-03:
(7*8)+(6*0)+(5*9)+(4*8)+(3*6)+(2*0)+(1*3)=154
154 % 10 = 4
So 80986-03-4 is a valid CAS Registry Number.
