105053-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105053-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,5 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 105053-49:
(8*1)+(7*0)+(6*5)+(5*0)+(4*5)+(3*3)+(2*4)+(1*9)=84
84 % 10 = 4
So 105053-49-4 is a valid CAS Registry Number.
