Check Digit Verification of cas no

The CAS Registry Mumber 1411894-76-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,1,8,9 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1411894-76:
(9*1)+(8*4)+(7*1)+(6*1)+(5*8)+(4*9)+(3*4)+(2*7)+(1*6)=162
162 % 10 = 2
So 1411894-76-2 is a valid CAS Registry Number.

Diastereoselective multicomponent cascade reaction leading to [3.2.0]-heterobicyclic compounds

Ausmees, Kerti,Kriis, Kadri,Pehk, T?nis,Werner, Franz,Jaì?rving, Ivar,Lopp, Margus,Kanger, T?nis

, p. 10680 - 10687 (2013/02/22)

A general three-component triple cascade reaction through an iminiuma-enaminea-iminium sequential activation initiated by a hetero-Michael addition to α,β-unsaturated aldehydes affords [3.2.0]heterobicycles in high diastereoselectivity. The rate and diastereoselectivity of the reaction depended on the (E)-4-heterocrotonate and size of the secondary amine. The enantiomers of the major diastereoisomer of oxa-and azabicyclo[3.2.0]heptane derivatives were separated by enzymatic kinetic resolution with immobilized Candida antarctica Lipase B (CALB), with E values up to 153. The absolute configuration of the nonacylated enantiomer of oxabicyclo[3.2.0]heptane was determined by single crystal X-ray analysis.
