21241-10-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21241-10-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,4 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21241-10:
(7*2)+(6*1)+(5*2)+(4*4)+(3*1)+(2*1)+(1*0)=51
51 % 10 = 1
So 21241-10-1 is a valid CAS Registry Number.
