Check Digit Verification of cas no

The CAS Registry Mumber 1246541-59-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,5,4 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1246541-59:
(9*1)+(8*2)+(7*4)+(6*6)+(5*5)+(4*4)+(3*1)+(2*5)+(1*9)=152
152 % 10 = 2
So 1246541-59-2 is a valid CAS Registry Number.

Novel diphenylmethyl-derived amide protecting group for efficient liquid-phase peptide synthesis: AJIPHASE

Takahashi, Daisuke,Yano, Tatsuya,Fukui, Tatsuya

, p. 4514 - 4517 (2012)

An efficient method for the synthesis of peptides bearing an amide at the C-terminal is described. This method involves the attachment of a C-terminal protecting group bearing long aliphatic chains, followed by the repetition of simple reaction and precipitation steps with the combined advantages of liquid-phase peptide synthesis (LPPS) and solid-phase peptide synthesis (SPPS). Using this method, a hydrophobic peptide was successfully synthesized in good yield and high purity, which cannot be obtained satisfactorily by SPPS.

PRODUCTION METHOD OF OLIGONUCLEOTIDE

-

, (2012/12/13)

The problem of the present invention is provision of a method of producing an n+p-mer oligonucleotide efficiently in a high yield, which includes use of, as a starting material, an n-mer oligonucleotide wherein the 3′-terminal hydroxyl group is protected,
