Check Digit Verification of cas no

The CAS Registry Mumber 1440529-30-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,5,2 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1440529-30:
(9*1)+(8*4)+(7*4)+(6*0)+(5*5)+(4*2)+(3*9)+(2*3)+(1*0)=135
135 % 10 = 5
So 1440529-30-5 is a valid CAS Registry Number.

Traceless Staudinger acetylation of azides in aqueous buffers

Sowa, Sylwia,Mühlberg, Michaela,Pietrusiewicz, K. Michal,Hackenberger, Christian P.R.

, p. 3465 - 3472 (2013/07/11)

In this paper, we demonstrate the applicability of water-soluble p-dimethylaminoethyl substituted phosphinomethanethiol in acetyl transfer reactions by the traceless Staudinger ligation with unprotected *-azido lysine containing peptides in aqueous buffer systems. Additionally, we present an improved synthesis pathway for the water-soluble phosphinothiol linkers requiring less steps in a comparable overall yield in comparison to previously published protocols.
