Check Digit Verification of cas no

The CAS Registry Mumber 174872-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,8,7 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 174872-57:
(8*1)+(7*7)+(6*4)+(5*8)+(4*7)+(3*2)+(2*5)+(1*7)=172
172 % 10 = 2
So 174872-57-2 is a valid CAS Registry Number.

Zinc-catalyzed amide cleavage and esterification of β- hydroxyethylamides

Kita, Yusuke,Nishii, Yuji,Higuchi, Takafumi,Mashima, Kazushi

, p. 5723 - 5726 (2012/08/07)

Snipping tool: Zn(OTf)2 is an efficient catalyst for selective cleavage of amides bearing a β-hydroxyethyl group on the nitrogen atom. The mechanism involves an N,O-acyl rearrangement and transesterification. This new catalytic system can be applied to sequence-specific peptide bond scission at the amine side of a serine residue. Tf=trifluoromethanesulfonyl. Copyright
