Check Digit Verification of cas no
The CAS Registry Mumber 117620-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,2 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117620-84:
(8*1)+(7*1)+(6*7)+(5*6)+(4*2)+(3*0)+(2*8)+(1*4)=115
115 % 10 = 5
So 117620-84-5 is a valid CAS Registry Number.
