Check Digit Verification of cas no

The CAS Registry Mumber 1169833-50-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,8,3 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1169833-50:
(9*1)+(8*1)+(7*6)+(6*9)+(5*8)+(4*3)+(3*3)+(2*5)+(1*0)=184
184 % 10 = 4
So 1169833-50-4 is a valid CAS Registry Number.

A synthetic approach to ervatamine-silicine alkaloids. Enantioselective total synthesis of (-)-16-episilicine

Amat, Mercedes,Llor, Nuria,Checa, Begona,Molins, Elies,Bosch, Joan

body text, p. 178 - 189 (2010/04/04)

(Chemical Equation Presented) Starting from an appropriate unsaturated phenylglycinol-derived oxazolopiperidone lactam, the synthesis of (-)-16-episilicine is reported, the key steps being a stereoselective conjugate addition, a stereoselective alkylation, and a ring-closing metathesis reaction. This represents the first enantioselective total synthesis of an alkaloid of the silicine group. 2009 American Chemical Society.

supporting information; experimental part, p. 2935 - 2937 (2009/11/30)

The first total synthesis of (-)-16-episilicine has been completed from a phenylglycinol-derived bicyclic lactam, the key steps being stereoselective conjugate addition and alkylation reactions, and a ring-closing metathesis.
