5281-79-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5281-79-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5281-79:
(6*5)+(5*2)+(4*8)+(3*1)+(2*7)+(1*9)=98
98 % 10 = 8
So 5281-79-8 is a valid CAS Registry Number.
