67705-42-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67705-42-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,0 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67705-42:
(7*6)+(6*7)+(5*7)+(4*0)+(3*5)+(2*4)+(1*2)=144
144 % 10 = 4
So 67705-42-4 is a valid CAS Registry Number.
