67309-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67309-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,0 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 67309-74:
(7*6)+(6*7)+(5*3)+(4*0)+(3*9)+(2*7)+(1*4)=144
144 % 10 = 4
So 67309-74-4 is a valid CAS Registry Number.
