Check Digit Verification of cas no
The CAS Registry Mumber 2748-88-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,4 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2748-88:
(6*2)+(5*7)+(4*4)+(3*8)+(2*8)+(1*8)=111
111 % 10 = 1
So 2748-88-1 is a valid CAS Registry Number.

Surface-active properties and their photochemical behaviors of H (1-Alkyl-4-pyridiniomethyl)phosphonates
Okamoto, Yoshiki,Hosoda, Asao,Takamuku, Setsuo
, p. 3053 - 3055 (2007/10/02)
( 1-Alkyl-4-pyridiniomethyl)phosphonates bearing long alkyl-chains of even carbon numbers of 8 to 18 were prepared. They exhibited the characteristics of surface-active agents. Upon irradiation in alkaline aqueous media, the phosphonates underwent the C-P bond cleavage to give 1-alkyl-4-methylpyridinium phosphates and as a result the surface tension of the solution also changed. The two-fold increases of the quantum yields of the C-P bond cleavage were found at their critical micelle concentrations.
