Check Digit Verification of cas no
The CAS Registry Mumber 28084-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,8 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28084-19:
(7*2)+(6*8)+(5*0)+(4*8)+(3*4)+(2*1)+(1*9)=117
117 % 10 = 7
So 28084-19-7 is a valid CAS Registry Number.
