156176-91-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156176-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,7 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 156176-91:
(8*1)+(7*5)+(6*6)+(5*1)+(4*7)+(3*6)+(2*9)+(1*1)=149
149 % 10 = 9
So 156176-91-9 is a valid CAS Registry Number.
