Check Digit Verification of cas no

The CAS Registry Mumber 152729-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,7,2 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 152729-82:
(8*1)+(7*5)+(6*2)+(5*7)+(4*2)+(3*9)+(2*8)+(1*2)=143
143 % 10 = 3
So 152729-82-3 is a valid CAS Registry Number.

Reactions of coordinated diazene in rhenium and tungsten complexes. Deprotonation of ligated NH=NH and subsequent H-migration to carbonyl ligands to give metal formyls

Cheng, Tan-Yun,Peters, Jonas C.,Hillhouse, Gregory L.

, p. 204 - 207 (2007/10/02)

The tungsten diazene complex [trans,trans- W(NH=NH)(CO)2(NO)(PPh3)2+][SO3CF3-] (1) reacts with NH2R (R = H, CH3, NH2) to give trans,trans-W(η1-OSO2CF3)(CO)2(NO)(PPh3)2 (2), trans,trans-W(H)(CO)2(NO)(PPh3)2 (3), and [trans,trans- W(NH2NH2)(CO)2(NO)(PPh3)2+][SO3CF3-] (4). If the reaction of NH2R with 1 is monitored at -78 °C, intermediates in the formation of 3 can be observed, which have been characterized as the neutral 6-coordinate formyl complexes trans-W(CH=O)(CO)(NO)(NH2R)(PPh3)2 (5a, R = H; 5b, R = CH3; 5c, R = NH2) on the basis of multinuclear (1H, 13C, 31P) NMR spectroscopy and 2H and 13C labeling experiments. The noncoordinating Bronsted base NaN(SiMe3)2 reacts with 1 to give 3 in 47% isolated yield, but because of the absence of a coordinating Lewis base, no formyl intermediate was observed. A reaction mechanism for the formation of hydride 3 is proposed involving (i) deprotonation of the diazene ligand in 1 by NH2R, (ii) H- migration from nitrogen to a carbonyl ligand to give the formyl complexes 5, and (iii) H-migration from the formyl ligand to the metal to give the neutral hydride product 3. The isoelectronic rhenium diazene complex [trans,mer- Re(NH=NH)(CO)3(PPh3)2+][SO3-CF3-] (9) has been prepared and shown to undergo a similar reaction with NH2CH3 to give trans,mer- Re(H)(CO)3(PPh3)2 (6) in 80% yield.
