Check Digit Verification of cas no

The CAS Registry Mumber 17293-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,9 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17293-74:
(7*1)+(6*7)+(5*2)+(4*9)+(3*3)+(2*7)+(1*4)=122
122 % 10 = 2
So 17293-74-2 is a valid CAS Registry Number.

Phosphorus-Nitrogen Compounds. Part 49. The Synthesis and Mechanism of Formation of 6-Chloro-5,6,7,12-tetrahydro-2,5,7,10-tetramethyldibenzo-diazaphosphocine 6-Oxide and 6-Sulphide

Demir, Tuersen,Shaw, Robert A.

, p. 1547 - 1552 (2007/10/02)

A reaction mechanism is proposed for the formation of the title compounds in the reactions between N,N-dimethyl-p-toluidine and phosphoryl and thiophosphoryl chlorides.The synthesis of 2,2'-methylenebis(p-toluidine) and 2,2'-methylenebis(N-methyl-p-toluidine) are described, as are their reactions with phosphoryl and thiophosphoryl chlorides.
