Check Digit Verification of cas no

The CAS Registry Mumber 98977-55-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,7 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98977-55:
(7*9)+(6*8)+(5*9)+(4*7)+(3*7)+(2*5)+(1*5)=220
220 % 10 = 0
So 98977-55-0 is a valid CAS Registry Number.

PH-Mediated Selective Synthesis of N-Allylic Alkylation or N-Alkylation Amines with Allylic Alcohols via an Iridium Catalyst in Water

Luo, Nianhua,Zhong, Yuhong,Shui, Hongling,Luo, Renshi

, p. 15509 - 15521 (2021/11/01)

Amination of allylic alcohols is an effective approach in the facile synthesis of N-allylic alkylation or N-alkylation amines. Recently, a series of catalysts were devised to push forward this transformation. However, current synthetic methods are typical

Palladium-catalyzed regio- and stereoselective β-arylation of tertiary allylic amines: Identification of potent adenylyl cyclase inhibitors

Ye, Zhishi,Dai, Mingji,Brust, Tarsis F.,Watts, Val J.

, p. 892 - 895 (2015/03/30)

Substituted allylic amines and their derivatives are key structural motifs of many drug molecules and natural products. A general, mild, and practical palladium-catalyzed β-arylation of tertiary allylic amines, one of the most challenging Heck arylation substrates, has been developed. The β-arylation products were obtained in excellent regio- and stereoselectivity. Moreover, novel and potent adenylyl cyclase inhibitors with the potential for treating neuropathic and inflammatory pain have been identified from the β-arylation products.
