128161-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128161-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,6 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128161-77:
(8*1)+(7*2)+(6*8)+(5*1)+(4*6)+(3*1)+(2*7)+(1*7)=123
123 % 10 = 3
So 128161-77-3 is a valid CAS Registry Number.
