4895-50-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4895-50-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,9 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4895-50:
(6*4)+(5*8)+(4*9)+(3*5)+(2*5)+(1*0)=125
125 % 10 = 5
So 4895-50-5 is a valid CAS Registry Number.
