127073-38-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127073-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,7 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127073-38:
(8*1)+(7*2)+(6*7)+(5*0)+(4*7)+(3*3)+(2*3)+(1*8)=115
115 % 10 = 5
So 127073-38-5 is a valid CAS Registry Number.
