343346-91-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 343346-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,3,4 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 343346-91:
(8*3)+(7*4)+(6*3)+(5*3)+(4*4)+(3*6)+(2*9)+(1*1)=138
138 % 10 = 8
So 343346-91-8 is a valid CAS Registry Number.
