234094-01-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 234094-01-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,4,0,9 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 234094-01:
(8*2)+(7*3)+(6*4)+(5*0)+(4*9)+(3*4)+(2*0)+(1*1)=110
110 % 10 = 0
So 234094-01-0 is a valid CAS Registry Number.
