1003193-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1003193-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,3,1,9 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1003193-22:
(9*1)+(8*0)+(7*0)+(6*3)+(5*1)+(4*9)+(3*3)+(2*2)+(1*2)=83
83 % 10 = 3
So 1003193-22-3 is a valid CAS Registry Number.
