34706-14-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34706-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,0 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34706-14:
(7*3)+(6*4)+(5*7)+(4*0)+(3*6)+(2*1)+(1*4)=104
104 % 10 = 4
So 34706-14-4 is a valid CAS Registry Number.
