127703-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127703-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127703-05:
(8*1)+(7*2)+(6*7)+(5*7)+(4*0)+(3*3)+(2*0)+(1*5)=113
113 % 10 = 3
So 127703-05-3 is a valid CAS Registry Number.
