109619-75-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109619-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,1 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109619-75:
(8*1)+(7*0)+(6*9)+(5*6)+(4*1)+(3*9)+(2*7)+(1*5)=142
142 % 10 = 2
So 109619-75-2 is a valid CAS Registry Number.
