34014-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34014-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,1 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34014-16:
(7*3)+(6*4)+(5*0)+(4*1)+(3*4)+(2*1)+(1*6)=69
69 % 10 = 9
So 34014-16-9 is a valid CAS Registry Number.
