193018-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193018-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,0,1 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 193018-44:
(8*1)+(7*9)+(6*3)+(5*0)+(4*1)+(3*8)+(2*4)+(1*4)=129
129 % 10 = 9
So 193018-44-9 is a valid CAS Registry Number.
