178267-91-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 178267-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,2,6 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 178267-91:
(8*1)+(7*7)+(6*8)+(5*2)+(4*6)+(3*7)+(2*9)+(1*1)=179
179 % 10 = 9
So 178267-91-9 is a valid CAS Registry Number.
