Check Digit Verification of cas no

The CAS Registry Mumber 1245618-54-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,6,1 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1245618-54:
(9*1)+(8*2)+(7*4)+(6*5)+(5*6)+(4*1)+(3*8)+(2*5)+(1*4)=155
155 % 10 = 5
So 1245618-54-5 is a valid CAS Registry Number.

Bromotriphenylphosphonium salt promoted tandem one-pot cyclization to optically active 2-Aryl-1,3-oxazolines

Jiang, Haizhen,Yuan, Shijie,Wan, Wen,Yang, Kun,Deng, Hongmei,Hao, Jian

experimental part, p. 4227 - 4236 (2010/10/04)

Optically active 2-aryl-1,3-oxazolines, such as aromatic carbocycles, heterocycle-binding 4-benzyl (or phenyl)-1,3oxazolines and their 5-benzyl (or phenyl)-l,3-oxazoline isomers were successfully prepared through a bromotriphenylphosphonium salt promoted aziridine ring formation and ring opening sequential process involving tandem one pot cyclization of chiral 2-amino-3-phenylpropanol or 2amino-2-phenylethanol with various aromatic acids in toluene at 90 °C in moderate to excellent yields. The mechanism of this tandem process was also substantiated experimentally.
