307340-16-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 307340-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,3,4 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 307340-16:
(8*3)+(7*0)+(6*7)+(5*3)+(4*4)+(3*0)+(2*1)+(1*6)=105
105 % 10 = 5
So 307340-16-5 is a valid CAS Registry Number.
