105495-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105495-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,4,9 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105495-21:
(8*1)+(7*0)+(6*5)+(5*4)+(4*9)+(3*5)+(2*2)+(1*1)=114
114 % 10 = 4
So 105495-21-4 is a valid CAS Registry Number.
