288623-07-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 288623-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,6,2 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 288623-07:
(8*2)+(7*8)+(6*8)+(5*6)+(4*2)+(3*3)+(2*0)+(1*7)=174
174 % 10 = 4
So 288623-07-4 is a valid CAS Registry Number.
