123417-00-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123417-00-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,1 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123417-00:
(8*1)+(7*2)+(6*3)+(5*4)+(4*1)+(3*7)+(2*0)+(1*0)=85
85 % 10 = 5
So 123417-00-5 is a valid CAS Registry Number.
