Check Digit Verification of cas no
The CAS Registry Mumber 10241-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,4 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10241-21:
(7*1)+(6*0)+(5*2)+(4*4)+(3*1)+(2*2)+(1*1)=41
41 % 10 = 1
So 10241-21-1 is a valid CAS Registry Number.
