254106-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 254106-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,1,0 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 254106-01:
(8*2)+(7*5)+(6*4)+(5*1)+(4*0)+(3*6)+(2*0)+(1*1)=99
99 % 10 = 9
So 254106-01-9 is a valid CAS Registry Number.
