1224442-42-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1224442-42-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,4,4 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1224442-42:
(9*1)+(8*2)+(7*2)+(6*4)+(5*4)+(4*4)+(3*2)+(2*4)+(1*2)=115
115 % 10 = 5
So 1224442-42-5 is a valid CAS Registry Number.
