111427-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111427-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 111427-20:
(8*1)+(7*1)+(6*1)+(5*4)+(4*2)+(3*7)+(2*2)+(1*0)=74
74 % 10 = 4
So 111427-20-4 is a valid CAS Registry Number.
