166828-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 166828-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,8,2 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 166828-77:
(8*1)+(7*6)+(6*6)+(5*8)+(4*2)+(3*8)+(2*7)+(1*7)=179
179 % 10 = 9
So 166828-77-9 is a valid CAS Registry Number.
