Check Digit Verification of cas no

The CAS Registry Mumber 178159-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,1,5 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 178159-74:
(8*1)+(7*7)+(6*8)+(5*1)+(4*5)+(3*9)+(2*7)+(1*4)=175
175 % 10 = 5
So 178159-74-5 is a valid CAS Registry Number.

Heterogeneous asymmetric epoxidation of unfunctionalized olefins catalyzed by polymer-bound (salen)manganese complexes

Minutolo, Filippo,Pini, Dario,Petri, Antonella,Salvadori, Piero

, p. 2293 - 2302 (1996)

The synthesis of three different polymer-bound chiral Mn-salen complexes (Poly-1, -2a, -2b) is reported, along with their application as recyclable catalysts in heterogeneous asymmetric epoxidation with mCPBA/NMO of several unfunctionalized olefins. The i

Heterogeneous chiral Mn(III) salen catalysts for the epoxidation of unfunctionalized olefins immobilized on mesoporous materials with different pore sizes

Yu, Kai,Gu, Zhicheng,Ji, Runan,Lou, Lan-Lan,Liu, Shuangxi

, p. 305 - 311 (2009)

Two chiral Mn(III) salen complexes were immobilized onto a series of mesoporous MCM-41 and MCM-48 materials with different pore sizes and the as-synthesized catalysts were active and enantioselective for the asymmetric epoxidation of styrene and indene. T

Chiral manganese(III) salen catalysts immobilized on MCM-41 and delaminated zeolites ITQ-2 and ITQ-6 through new axial coordinating linkers

Dominguez, Irene,Fornes, Vicente,Sabater, Maria J.

, p. 92 - 99 (2007/10/03)

We report that the catalytic behavior and enantioselectivity of three different chiral Mn(III) salen complexes anchored to traditional supports such as MCM-41 (38-A pore diameter) and delaminated zeolitic materials ITQ-2 and ITQ-6 strongly depend on wheth
