113756-87-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 113756-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,7,5 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 113756-87:
(8*1)+(7*1)+(6*3)+(5*7)+(4*5)+(3*6)+(2*8)+(1*7)=129
129 % 10 = 9
So 113756-87-9 is a valid CAS Registry Number.

Practical Peptide Synthesis Mediated by a Recyclable Hypervalent Iodine Reagent and Tris(4-methoxyphenyl)phosphine

Zhang, Chi,Liu, Shan-Shan,Sun, Bo,Tian, Jun

supporting information, p. 4106 - 4109 (2015/09/01)

6-(3,5-Bis(trifluoromethyl)phenyl)-1H,4H-2aλ3-ioda-2,3-dioxacyclopenta[hi]indene-1,4-dione (p-BTFP-iodosodilactone, 1a) was synthesized and demonstrated to be an efficient hypervalent iodine(III) reagent for the synthesis of dipeptides from various standard amino acids, including sterically hindered amino acids, in good to high yields within 30 min in the presence of tris(4-methoxyphenyl)phosphine. In addition, the combined system of 1a/(4-MeOC6H4)3P was used to synthesize the pentapeptide leu-enkephalin in protected form. It is worth noting that 1a can be regenerated readily after reaction.
