Check Digit Verification of cas no
The CAS Registry Mumber 117490-51-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,4,9 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117490-51:
(8*1)+(7*1)+(6*7)+(5*4)+(4*9)+(3*0)+(2*5)+(1*1)=124
124 % 10 = 4
So 117490-51-4 is a valid CAS Registry Number.
