127394-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127394-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,3,9 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127394-40:
(8*1)+(7*2)+(6*7)+(5*3)+(4*9)+(3*4)+(2*4)+(1*0)=135
135 % 10 = 5
So 127394-40-5 is a valid CAS Registry Number.
