288403-14-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 288403-14-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,4,0 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 288403-14:
(8*2)+(7*8)+(6*8)+(5*4)+(4*0)+(3*3)+(2*1)+(1*4)=155
155 % 10 = 5
So 288403-14-5 is a valid CAS Registry Number.
