105018-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105018-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,1 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105018-31:
(8*1)+(7*0)+(6*5)+(5*0)+(4*1)+(3*8)+(2*3)+(1*1)=73
73 % 10 = 3
So 105018-31-3 is a valid CAS Registry Number.
