Check Digit Verification of cas no

The CAS Registry Mumber 16428-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,2 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16428-57:
(7*1)+(6*6)+(5*4)+(4*2)+(3*8)+(2*5)+(1*7)=112
112 % 10 = 2
So 16428-57-2 is a valid CAS Registry Number.

Paragraph 0028, (2021/03/03)

The invention relates to an alpha, beta-deuterated amine compound, a deuterated drug and a reduction deuteration method of a nitrile organic matter for synthesizing the alpha, beta-deuterated amine compound. The method is characterized by comprising the f

Facile one-pot synthesis of 2-aryl-substituted nitriles and 2-aryl-3-keto nitriles via benzyne reaction

Kamila, Sukanta,Koh, Benjamin,Biehl, Edward R.

, p. 3493 - 3507 (2007/10/03)

2-Aryl-substituted nitriles were prepared in good to excellent yields in a one-pot reaction by the reaction of benzyne, generated using neutral conditions from (phenyl)[o-(trimethylsilyl)-phenyl]iodonium triflate, and 2-lithionitriles. 3-Keto nitriles substituted at the 2-position were obtained in good yields when these reactions were trapped with acid chlorides. The mechanism of the benzyne reaction in terms of a N-lithiobenzocyclobutanimine intermediate is discussed. Copyright Taylor & Francis Group, LLC.
