851666-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 851666-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,6,6 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 851666-23:
(8*8)+(7*5)+(6*1)+(5*6)+(4*6)+(3*6)+(2*2)+(1*3)=184
184 % 10 = 4
So 851666-23-4 is a valid CAS Registry Number.

The stereoselective addition of titanium(IV) enolates of 1,3-oxazolidin-2-one and 1,3-thiazolidine-2-thione to cyclic N-acyliminium ion. The total synthesis of (+)-isoretronecanol

Pereira, Elaine,De Fátima Alves, Concei??o,B?ckelmann, Maria Alice,Pilli, Ronaldo A.

, p. 2691 - 2693 (2005)

(+)-Isoretronecanol (1) has been prepared in four steps and 36% overall yield via the diastereoselective addition of the titanium(IV) enolate derived from N-4-chlorobutyryl-1,3-thiazolidine-2-thione (3) to N-Boc-2- methoxypyrrolidine (5), which afforded 2-substituted pyrrolidine 7 in 84% yield (8:1 diastereoisomeric ratio), followed by reductive recovery of the chiral auxiliary and cyclization.
