193401-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193401-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,4,0 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 193401-42:
(8*1)+(7*9)+(6*3)+(5*4)+(4*0)+(3*1)+(2*4)+(1*2)=122
122 % 10 = 2
So 193401-42-2 is a valid CAS Registry Number.
