123458-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123458-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,5 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123458-84:
(8*1)+(7*2)+(6*3)+(5*4)+(4*5)+(3*8)+(2*8)+(1*4)=124
124 % 10 = 4
So 123458-84-4 is a valid CAS Registry Number.
