127426-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127426-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,4,2 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127426-53:
(8*1)+(7*2)+(6*7)+(5*4)+(4*2)+(3*6)+(2*5)+(1*3)=123
123 % 10 = 3
So 127426-53-3 is a valid CAS Registry Number.
