105198-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105198-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,1,9 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 105198-22:
(8*1)+(7*0)+(6*5)+(5*1)+(4*9)+(3*8)+(2*2)+(1*2)=109
109 % 10 = 9
So 105198-22-9 is a valid CAS Registry Number.
