289665-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 289665-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,6,6 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 289665-40:
(8*2)+(7*8)+(6*9)+(5*6)+(4*6)+(3*5)+(2*4)+(1*0)=203
203 % 10 = 3
So 289665-40-3 is a valid CAS Registry Number.
