123500-84-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123500-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,0 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123500-84:
(8*1)+(7*2)+(6*3)+(5*5)+(4*0)+(3*0)+(2*8)+(1*4)=85
85 % 10 = 5
So 123500-84-5 is a valid CAS Registry Number.
