Check Digit Verification of cas no

The CAS Registry Mumber 1612261-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,2,2,6 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1612261-68:
(9*1)+(8*6)+(7*1)+(6*2)+(5*2)+(4*6)+(3*1)+(2*6)+(1*8)=133
133 % 10 = 3
So 1612261-68-3 is a valid CAS Registry Number.

Homogeneous hydrogenation of nitriles catalyzed by molybdenum and tungsten amides

Chakraborty, Subrata,Berke, Heinz

, p. 2191 - 2194 (2014/07/21)

Low-valent molybdenum and tungsten amides M(NO)(CO)(PNP) {M = Mo, 1a; W, 1b; PNP = N(CH2CH2PiPr2) 2} were found to be active catalysts for the hydrogenation of various nitriles to the corresponding imines, primary amines, and N-substituted imines with high selectivity for the latter type of product. A wide range of p-and m-substituted aromatic nitriles-p-methyl, p-methoxy, p-bromobenzonitriles; 3-trifluoromethylbenzonitrile, m-and p-disubstituted benzonitrile; the heterocyclic 2-thiophencarbonitrile; and the aliphatic nitriles cyclohexylcarbonitrile and benzylcyanide-could be hydrogenated at 140 °C and 60 bar H2 in THF with high yields. TOFs were found to be between 0.4 and 36 h-1.
