176438-84-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 176438-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,4,3 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 176438-84:
(8*1)+(7*7)+(6*6)+(5*4)+(4*3)+(3*8)+(2*8)+(1*4)=169
169 % 10 = 9
So 176438-84-9 is a valid CAS Registry Number.
