853221-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 853221-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,2,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 853221-21:
(8*8)+(7*5)+(6*3)+(5*2)+(4*2)+(3*1)+(2*2)+(1*1)=143
143 % 10 = 3
So 853221-21-3 is a valid CAS Registry Number.

, p. 1907 - 1910 (2007/10/03)
(Chemical Equation Presented) Four generations of phenylenefluorene (1F)- and phenylenebis(fluorene) (2F)-terminated polyamidoamine (PAMAM) dendrimers were synthesized by coupling activated esters with commercially available PAMAM precursors. Treatment of
