Check Digit Verification of cas no
The CAS Registry Mumber 519-67-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 519-67:
(5*5)+(4*1)+(3*9)+(2*6)+(1*7)=75
75 % 10 = 5
So 519-67-5 is a valid CAS Registry Number.
