1262390-50-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1262390-50-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,3,9 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1262390-50:
(9*1)+(8*2)+(7*6)+(6*2)+(5*3)+(4*9)+(3*0)+(2*5)+(1*0)=140
140 % 10 = 0
So 1262390-50-0 is a valid CAS Registry Number.
