The CAS Registry Mumber 777864-66-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,7,8,6 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 777864-66:
(8*7)+(7*7)+(6*7)+(5*8)+(4*6)+(3*4)+(2*6)+(1*6)=241
241 % 10 = 1
So 777864-66-1 is a valid CAS Registry Number.

Synthesis of caged nucleosides with photoremovable protecting groups linked to intramolecular antennae

Smirnova, Joulia,Woell, Dominik,Pfleiderer, Wolfgang,Steiner, Ulrich E.

, p. 891 - 904 (2007/10/03)

Based on the [2-(2-nitrophenyl)propoxy]carbonyl (nppoc) group, six new photolabile protecting groups (2, 8, 9b, 16b, 25b, and 26), each covalently linked to a 9H-thioxanthen-9-one (Tx) unit functioning as an intramolecular triplet sensitizer, were synthes
