Check Digit Verification of cas no

The CAS Registry Mumber 1236057-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,0,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1236057-20:
(9*1)+(8*2)+(7*3)+(6*6)+(5*0)+(4*5)+(3*7)+(2*2)+(1*0)=127
127 % 10 = 7
So 1236057-20-7 is a valid CAS Registry Number.

Visible-Light-Promoted Alkylation of Indoles with Tertiary Amines by the Oxidation of a sp3 C-H Bond

Ding, Xuan,Dong, Chun-Lin,Guan, Zhi,He, Yan-Hong

, p. 762 - 767 (2017/12/26)

A visible-light driven reaction for the synthesis of 3-arylmethyl indole derivatives using tertiary amines and indoles was first reported. Corresponding products were obtained with yields of up to 70%, and various functional groups on the indoles were well tolerated when Rose Bengal was used as a photosensitizer and air was used as a green oxidant under mild reaction conditions. (Figure presented.).

Ruthenium-catalyzed alkylation of indoles with tertiary amines by oxidation of a sp3 CH bond and lewis acid catalysis

Wang, Ming-Zhong,Zhou, Cong-Ying,Wong, Man-Kin,Che, Chi-Ming

experimental part, p. 5723 - 5735 (2010/08/20)

Ruthenium porphyrins (particularly [Ru(2,6-Cl2tpp)CO]; tpp = tetraphenylporphinato) and RuCl3 can act as oxidation and/or Lewis acid catalysts for direct C-3 alkylation of indoles, giving the desired products in high yields (up to 82
