345207-09-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 345207-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,2,0 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 345207-09:
(8*3)+(7*4)+(6*5)+(5*2)+(4*0)+(3*7)+(2*0)+(1*9)=122
122 % 10 = 2
So 345207-09-2 is a valid CAS Registry Number.
