The CAS Registry Mumber 267005-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,7,0,0 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 267005-08:
(8*2)+(7*6)+(6*7)+(5*0)+(4*0)+(3*5)+(2*0)+(1*8)=123
123 % 10 = 3
So 267005-08-3 is a valid CAS Registry Number.

Synthesis of water soluble derivatives of milbemycin D

Matsueda, Rei,Higashida, Susumu

, p. 511 - 514 (2007/10/03)

Water Soluble 5-O-(S-glutathionylthio)cysteinyl-milbemycin D was successfully synthesized by using 3-nitro-2-pyridinesulfenyl (Npys) reagent through esterification of a Boc-cysteine derivative to a hydroxyl group at the C-5 position of milbemycin D, activation of the conventional S-protecting group, and asymmetrical disulfide bond formation.
