Check Digit Verification of cas no

The CAS Registry Mumber 1329451-08-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,9,4,5 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1329451-08:
(9*1)+(8*3)+(7*2)+(6*9)+(5*4)+(4*5)+(3*1)+(2*0)+(1*8)=152
152 % 10 = 2
So 1329451-08-2 is a valid CAS Registry Number.

Asymmetric vinylogous Mannich reactions: A versatile approach to functionalized heterocycles

Ruan, Shu-Tang,Luo, Jie-Min,Du, Yu,Huang, Pei-Qiang

, p. 4938 - 4941 (2011/11/06)

Asymmetric vinylogous Mannich reaction (VMR) of 2-(tert- butyldimethylsilyloxy)furan (TBSOF, 1) with (RS)- or (S S)-t-BS-imines (3) furnished 5-aminoalkylbutenolides 7a-k in 75-87% yields with anti/syn ratios ranging from 75:25 to 97:3. Butenolides 7a-f,k were readily converted into substituted lactones 8 and 5 and 6-substituted 5-hydroxypiperidin-2-ones 11a-g, which are, in turn, key intermediates for the synthesis of many bioactive compounds.
