286938-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 286938-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,6,9,3 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 286938-20:
(8*2)+(7*8)+(6*6)+(5*9)+(4*3)+(3*8)+(2*2)+(1*0)=193
193 % 10 = 3
So 286938-20-3 is a valid CAS Registry Number.
