Check Digit Verification of cas no

The CAS Registry Mumber 1346756-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,7,5 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1346756-52:
(9*1)+(8*3)+(7*4)+(6*6)+(5*7)+(4*5)+(3*6)+(2*5)+(1*2)=182
182 % 10 = 2
So 1346756-52-2 is a valid CAS Registry Number.

HMDO-promoted peptide and protein synthesis in ionic liquids

, p. 7013 - 7022 (2013/08/23)

Hexamethyldisiloxane (HMDO) has been developed to efficiently promote the metal-free direct coupling of an amino function of one cysteine-free peptide or protein and a C-terminal thioester of the second peptide in ionic liquids. The amide-coupling reaction proceeds smoothly under mild conditions to afford the corresponding products in good to excellent yields (63-94%). Peptide couplings were also achieved using in-situ-generated thioesters by the thioesterification of oxo esters.
