67240-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67240-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,4 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67240-28:
(7*6)+(6*7)+(5*2)+(4*4)+(3*0)+(2*2)+(1*8)=122
122 % 10 = 2
So 67240-28-2 is a valid CAS Registry Number.
