Check Digit Verification of cas no
The CAS Registry Mumber 21406-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,0 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21406-51:
(7*2)+(6*1)+(5*4)+(4*0)+(3*6)+(2*5)+(1*1)=69
69 % 10 = 9
So 21406-51-9 is a valid CAS Registry Number.
