123558-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123558-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,5 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123558-72:
(8*1)+(7*2)+(6*3)+(5*5)+(4*5)+(3*8)+(2*7)+(1*2)=125
125 % 10 = 5
So 123558-72-5 is a valid CAS Registry Number.
