288-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 288-40-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 288-40:
(5*2)+(4*8)+(3*8)+(2*4)+(1*0)=74
74 % 10 = 4
So 288-40-4 is a valid CAS Registry Number.
