1114455-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1114455-30-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,4,4,5 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1114455-30:
(9*1)+(8*1)+(7*1)+(6*4)+(5*4)+(4*5)+(3*5)+(2*3)+(1*0)=109
109 % 10 = 9
So 1114455-30-9 is a valid CAS Registry Number.
