847658-67-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 847658-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,6,5 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 847658-67:
(8*8)+(7*4)+(6*7)+(5*6)+(4*5)+(3*8)+(2*6)+(1*7)=227
227 % 10 = 7
So 847658-67-7 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
