Check Digit Verification of cas no

The CAS Registry Mumber 104144-02-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,1,4 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104144-02:
(8*1)+(7*0)+(6*4)+(5*1)+(4*4)+(3*4)+(2*0)+(1*2)=67
67 % 10 = 7
So 104144-02-7 is a valid CAS Registry Number.

Utilization of Phenylthio Substituted Amines for the Synthesis of Pyrrolidines

Padwa, Albert,Dent, William,Nimmesgern, Hildegard,Venkatramanan, M. K.,Wong, George S. K.

, p. 813 - 828 (2007/10/02)

α-Phenylthio substituted amines have been found to be convenient reagents for the preparation of the pyrrolidine ring.Benzylamine (2) undergoes 1,3-dipolar cycloaddition with several dipolarophiles in the presence of silver fluoride.The reaction is believed to proceed via the intermediacy of an azomethine ylide.Treatment of α-(phenylthio)cyanoamines 10 and 17 with strong base results in the loss of the phenylthio group, and formation of substituted trans-piperazines 21, 22 in the case of 17.The mechanism of the reaction involves dimerization of the initially formed cyano substituted azomethine ylide intermediate, which behaves as a captodative diradical.Finally, the reaction of several alkenylamines with tributyltin hydride was studied as a method for generating the pyrrolidine ring via a radical cyclization reaction.
