Check Digit Verification of cas no

The CAS Registry Mumber 68048-50-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,4 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68048-50:
(7*6)+(6*8)+(5*0)+(4*4)+(3*8)+(2*5)+(1*0)=140
140 % 10 = 0
So 68048-50-0 is a valid CAS Registry Number.

Polystyrene-supported proline and prolinamide. Versatile heterogeneous organocatalysts both for asymmetric aldol reaction in water and α-selenenylation of aldehydes

Giacalone, Francesco,Gruttadauria, Michelangelo,Marculescu, Adriana Mossuto,Noto, Renato

, p. 255 - 259 (2007)

A simple and efficient synthesis of polystyrene-supported proline and prolinamide has been carried out. Polystyrene-supported proline has been used as organocatalyst in the asymmetric aldol reaction between cyclohexanone and substituted benzaldehydes in w

α-Phenylselenenylation of aldehydes and ketones with diphenyl diselenide mediated by KF/Al2O3

Nazari, Mohammad,Movassagh, Barahman

experimental part, p. 1453 - 1455 (2009/05/31)

The utility of KF/Al2O3 for the synthesis of α-phenylseleno aldehydes and ketones from the corresponding aldehydes or ketones and diphenyl diselenide has been investigated. Simple stirring of a mixture of aldehyde or ketone and diphe

Direct, facile aldehyde and ketone α-selenenylation reactions promoted by L-prolinamide and pyrrolidine sulfonamide organocatalysts

Wang, Jian,Li, Hao,Mei, Yujiang,Lou, Bihshow,Xu, Dingguo,Xie, Daiqian,Guo, Hua,Wang, Wei

, p. 5678 - 5687 (2007/10/03)

A new catalytic method for direct α-selenenylation reactions of aldehydes and ketones has been developed. The results of exploratory studies have demonstrated that L-prolinamide is an effective catalyst for α-selenenylation reactions of aldehydes, whereas
