109873-30-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109873-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,7 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109873-30:
(8*1)+(7*0)+(6*9)+(5*8)+(4*7)+(3*3)+(2*3)+(1*0)=145
145 % 10 = 5
So 109873-30-5 is a valid CAS Registry Number.
