21003-99-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21003-99-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,0 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21003-99:
(7*2)+(6*1)+(5*0)+(4*0)+(3*3)+(2*9)+(1*9)=56
56 % 10 = 6
So 21003-99-6 is a valid CAS Registry Number.
