252846-38-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 252846-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,8,4 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 252846-38:
(8*2)+(7*5)+(6*2)+(5*8)+(4*4)+(3*6)+(2*3)+(1*8)=151
151 % 10 = 1
So 252846-38-1 is a valid CAS Registry Number.

α-chymotrypsin-catalysed segment condensations via the kinetically controlled approach using carbamoylmethyl esters as acyl donors in organic media

Miyazawa, Toshifumi,Ensatsu, Eiichi,Hiramatsu, Makoto,Yanagihara, Ryoji,Yamada, Takashi

, p. 396 - 401 (2007/10/03)

The superiority of the carbamoylmethyl ester as an acyl donor for the α-chymotrypsin-catalysed segment condensations via the kinetically controlled approach is demonstrated in several model systems carried out in organic media with low water content. Furthermore, this approach is successfully applied to the construction of the Leu-enkephalin sequence via a 4 + 1 segment coupling.
