1243260-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1243260-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,2,6 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1243260-57:
(9*1)+(8*2)+(7*4)+(6*3)+(5*2)+(4*6)+(3*0)+(2*5)+(1*7)=122
122 % 10 = 2
So 1243260-57-2 is a valid CAS Registry Number.
