7309-88-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7309-88-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,0 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7309-88:
(6*7)+(5*3)+(4*0)+(3*9)+(2*8)+(1*8)=108
108 % 10 = 8
So 7309-88-8 is a valid CAS Registry Number.
