5305-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5305-81-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,0 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.Calculate Digit Verification of CAS Registry Number 5305-81:
(6*5)+(5*3)+(4*0)+(3*5)+(2*8)+(1*1)=77
77 % 10 = 7
So 5305-81-7 is a valid CAS Registry Number.
