23909-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23909-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,0 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23909-34:
(7*2)+(6*3)+(5*9)+(4*0)+(3*9)+(2*3)+(1*4)=114
114 % 10 = 4
So 23909-34-4 is a valid CAS Registry Number.
