Check Digit Verification of cas no
The CAS Registry Mumber 6424-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6424-71:
(6*6)+(5*4)+(4*2)+(3*4)+(2*7)+(1*1)=91
91 % 10 = 1
So 6424-71-1 is a valid CAS Registry Number.
