1899-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1899-80-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.Calculate Digit Verification of CAS Registry Number 1899-80:
(6*1)+(5*8)+(4*9)+(3*9)+(2*8)+(1*0)=125
125 % 10 = 5
So 1899-80-5 is a valid CAS Registry Number.
