(1S)-1-(7-Benzylselanyl-1(2)H-pyrazolo[4,3-d]pyrimidin-3-yl)-D-1,4-anhydro-ribitol is a complex organic compound with a unique molecular structure. It features a pyrazolo[4,3-d]pyrimidin-3-yl core, which is a heterocyclic ring system with a pyrazole and a pyrimidine fused together. The 7-benzylselanyl group, which includes a benzyl and a seleno group, is attached to this core, providing a significant steric and electronic influence. The D-1,4-anhydro-ribitol part of the molecule is a modified ribitol, a sugar alcohol, with the 1,4-anhydro bridge, which means the hydroxyl groups at positions 1 and 4 are connected, forming a cyclic ether. (1S)-1-(7-benzylselanyl-1(2)H-pyrazolo[4,3-d]pyrimidin-3-yl)-D-1,4-anhydro-ribitol is characterized by its chirality, with the (1S) configuration indicating the specific arrangement of atoms around the chiral center. The compound's structure and properties make it potentially interesting for various applications in chemistry and biology, such as pharmaceuticals or materials science.
The CAS Registry Mumber 39102-67-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,0 and 2 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 39102-67: (7*3)+(6*9)+(5*1)+(4*0)+(3*2)+(2*6)+(1*7)=105 105 % 10 = 5 So 39102-67-5 is a valid CAS Registry Number.
