1250260-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1250260-83-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,0,2,6 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1250260-83:
(9*1)+(8*2)+(7*5)+(6*0)+(5*2)+(4*6)+(3*0)+(2*8)+(1*3)=113
113 % 10 = 3
So 1250260-83-3 is a valid CAS Registry Number.
