162828-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162828-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,8,2 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 162828-18:
(8*1)+(7*6)+(6*2)+(5*8)+(4*2)+(3*8)+(2*1)+(1*8)=144
144 % 10 = 4
So 162828-18-4 is a valid CAS Registry Number.
