Check Digit Verification of cas no
The CAS Registry Mumber 5419-77-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,1 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5419-77:
(6*5)+(5*4)+(4*1)+(3*9)+(2*7)+(1*7)=102
102 % 10 = 2
So 5419-77-2 is a valid CAS Registry Number.
