193018-46-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193018-46-1 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 193018-46:
(8*1)+(7*9)+(6*3)+(5*0)+(4*1)+(3*8)+(2*4)+(1*6)=131
131 % 10 = 1
So 193018-46-1 is a valid CAS Registry Number.
