Check Digit Verification of cas no

The CAS Registry Mumber 61486-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,8 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61486-91:
(7*6)+(6*1)+(5*4)+(4*8)+(3*6)+(2*9)+(1*1)=137
137 % 10 = 7
So 61486-91-7 is a valid CAS Registry Number.

Semisynthetic Macrolide Antibacterials Derived from Tylosin. Synthesis of 3-O-Acetyl-23-O-demycinosyl-4''-O-isovaleryltylosin and Related Compounds, as well as the 12,13-Epoxy Derivatives

Fishman, Andrew G.,Mallams, Alan K.,Rossman, Randall R.

, p. 787 - 798 (2007/10/02)

Selective acylation techniques have been developed that enable the synthesis of 3-O-acetyl-4''-O-isovaleryltylosin and 3-O-acetyl-23-O-demycinosyl-4''-O-isovaleryltylosin to be carried out in an efficient manner starting from tylosin.The syntheses of the 2'-O-acetyl, 23-O-acetyl, and 2',23-di-O-acetyl derivatives of the latter are also described.The synthesis of key hydrazones is also described.The regio- and stereo-selective epoxidation of tylosin and its acyl derivatives afforded the 12,13-epoxyanalogues, which were used to synthesize novel acylated 12,13-epoxy derivatives of 23-O-demycinosyltylosin.
