Check Digit Verification of cas no

The CAS Registry Mumber 1213786-18-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,7,8 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1213786-18:
(9*1)+(8*2)+(7*1)+(6*3)+(5*7)+(4*8)+(3*6)+(2*1)+(1*8)=145
145 % 10 = 5
So 1213786-18-5 is a valid CAS Registry Number.

Aniline-initiated and Br?nsted acid-catalyzed one-pot reaction toward 2-aryl-3-sulfenylindoles by using α-aminocarbonyl compounds and primary amines with RSSR

Chen, De,Cheng, Chaozhihui,Deng, Wei,Guan, Wenjian,Liu, Yuxuan,Luo, Yongyue,Xiang, Jiannan,Zhang, Jiajia

, (2020/12/01)

A highly novel method of direct synthesis of 2-aryl-3-sulfenylindoles in moderate to good yields was developed via one-pot tandem reaction of readily available α-aminocarbonyl compounds and catalytic amount of benzenamines with RSSR.

Metal-free synthesis of 3-sulfenylindoles via an iodine-mediated electrophilic cyclisation of 2-alkynylanilines with disulfides

Tao, Li-Ming,Liu, Wen-Qi,Zhou, Yun,Li, Ai-Tao

, p. 644 - 646 (2013/02/22)

An efficient and metal-free method was developed to synthesise 3-sulfenylindoles via the iodine-mediated electrophilic cyclisation of 2-alkynylanilines with disulfides. In the presence of I2, various 3-sulfenylindoles were obtained in moderate
