Check Digit Verification of cas no
The CAS Registry Mumber 5751-84-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5751-84:
(6*5)+(5*7)+(4*5)+(3*1)+(2*8)+(1*4)=108
108 % 10 = 8
So 5751-84-8 is a valid CAS Registry Number.
