1244540-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1244540-57-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,4,5,4 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1244540-57:
(9*1)+(8*2)+(7*4)+(6*4)+(5*5)+(4*4)+(3*0)+(2*5)+(1*7)=135
135 % 10 = 5
So 1244540-57-5 is a valid CAS Registry Number.
