123401-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123401-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,0 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123401-54:
(8*1)+(7*2)+(6*3)+(5*4)+(4*0)+(3*1)+(2*5)+(1*4)=77
77 % 10 = 7
So 123401-54-7 is a valid CAS Registry Number.
