General Description
"(1S,3aR,6aS)-Octahydrocyclopenta[c]pyrrole-1-carboxylic acid ethyl ester hydrochloride is a chemical compound with a specific stereochemistry, as indicated by the 1S, 3aR, 6aS designation, which refers to the spatial orientation of different parts of the molecule. The mention of 'octahydrocyclopenta[c]pyrrole' in its name suggests that this complex organic molecule contains a cyclopentapyrrole group - a ring-like structure made of five carbon atoms and a nitrogen atom. '1-carboxylic acid ethyl ester' indicates the presence of a carboxylic acid ester functional group, specifically, an ethyl ester, attached at the first position of the ring structure. The 'hydrochloride' at the end of the name denotes that it is a salt formed with hydrochloric acid. Details about its chemical properties, uses or synthesis are not specified in the name itself.
Check Digit Verification of cas no
The CAS Registry Mumber 1147103-42-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,7,1,0 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1147103-42:
(9*1)+(8*1)+(7*4)+(6*7)+(5*1)+(4*0)+(3*3)+(2*4)+(1*2)=111
111 % 10 = 1
So 1147103-42-1 is a valid CAS Registry Number.
