The CAS Registry Mumber 117838-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,3 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117838-27:
(8*1)+(7*1)+(6*7)+(5*8)+(4*3)+(3*8)+(2*2)+(1*7)=144
144 % 10 = 4
So 117838-27-4 is a valid CAS Registry Number.
