67628-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67628-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,2 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 67628-45:
(7*6)+(6*7)+(5*6)+(4*2)+(3*8)+(2*4)+(1*5)=159
159 % 10 = 9
So 67628-45-9 is a valid CAS Registry Number.
