1224442-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1224442-31-2 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, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1224442-31:
(9*1)+(8*2)+(7*2)+(6*4)+(5*4)+(4*4)+(3*2)+(2*3)+(1*1)=112
112 % 10 = 2
So 1224442-31-2 is a valid CAS Registry Number.
