176685-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176685-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,6,8 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 176685-91:
(8*1)+(7*7)+(6*6)+(5*6)+(4*8)+(3*5)+(2*9)+(1*1)=189
189 % 10 = 9
So 176685-91-9 is a valid CAS Registry Number.
