109775-00-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109775-00-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,7 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109775-00:
(8*1)+(7*0)+(6*9)+(5*7)+(4*7)+(3*5)+(2*0)+(1*0)=140
140 % 10 = 0
So 109775-00-0 is a valid CAS Registry Number.
