109911-53-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109911-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,1 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109911-53:
(8*1)+(7*0)+(6*9)+(5*9)+(4*1)+(3*1)+(2*5)+(1*3)=127
127 % 10 = 7
So 109911-53-7 is a valid CAS Registry Number.
