34494-89-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34494-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,4,9 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 34494-89:
(7*3)+(6*4)+(5*4)+(4*9)+(3*4)+(2*8)+(1*9)=138
138 % 10 = 8
So 34494-89-8 is a valid CAS Registry Number.
