105984-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105984-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,8 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105984-81:
(8*1)+(7*0)+(6*5)+(5*9)+(4*8)+(3*4)+(2*8)+(1*1)=144
144 % 10 = 4
So 105984-81-4 is a valid CAS Registry Number.
