126404-54-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126404-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,0 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 126404-54:
(8*1)+(7*2)+(6*6)+(5*4)+(4*0)+(3*4)+(2*5)+(1*4)=104
104 % 10 = 4
So 126404-54-4 is a valid CAS Registry Number.
