Check Digit Verification of cas no

The CAS Registry Mumber 94071-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,0,7 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94071-21:
(7*9)+(6*4)+(5*0)+(4*7)+(3*1)+(2*2)+(1*1)=123
123 % 10 = 3
So 94071-21-3 is a valid CAS Registry Number.

Synthesis of mycolic acid biosurfactants and their physical and surface-active properties

Lee, Myungjin,Gwak, Hyung Sub,Park, Byeong Deog,Lee, Sung-Taik

, p. 181 - 188 (2005)

Five mycolic acids [2-alkyl-3-hydroxy FA: R 1C*H(OH)C*HR2COOH] were synthesized using acyl chlorides with alkyl chains of different lengths (total carbon numbers of mycolic acids, 12, 16, 20, 24, 36). The relationship between the chemical structures of the mycolic acids and their surface-active properties was determined. The acids were synthesized in three steps: (i) dimerization of acyl chloride into alkyl ketene dimer, (ii) selective reduction of C=C to C-C by hydrogenation, and (iii) βlactone ring cleavage under alkaline conditions. The yields of C12-, C16-, C20-, C 24-, and C36-mycolic acid were 72, 73, 73, 73, and 73%, respectively. The critical micelle concentrations (CMC) of C12-, C16-, and C20-mycolic acid were 2.2 × 10 -4, 1.36 × 10-4, and 7.4 × 10-5 M, respectively. As the carbon number increased, the surface tension at the CMC value was also lower; the values for C12-, C16-, and C20-mycolic acid were 46.54, 43.59, and 41.57 dyn/cm, respectively. The emulsifying activities of mycolic acids were determined for n-tetradecane, n-hexadecane, cyclohexane, and diesel oil. The results showed that C 12-mycolic acid was the best emulsifier for diesel oil, C 16-mycolic acid was the best emulsifier for n-tetradecane and n-hexadecane, and C20-mycolic acid was the best emulsifier for cyclohexane. This study showed that mycolic acids having surface-active properties can be chemically synthesized for potential applications in the detergent/cleaning material industries, for example, in oil spill cleanup, oil recovery, textiles, pharmaceuticals, and cosmetics.
