Check Digit Verification of cas no

The CAS Registry Mumber 1287693-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,6,9 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1287693-75:
(9*1)+(8*2)+(7*8)+(6*7)+(5*6)+(4*9)+(3*3)+(2*7)+(1*5)=217
217 % 10 = 7
So 1287693-75-7 is a valid CAS Registry Number.

Gold(I)-catalyzed rearrangement of alkynylaziridine indoles for the synthesis of spiro-tetrahydro-β-carbolines

Yang, Yan-Fang,Li, Lian-Hua,He, Yu-Tao,Luo, Jian-Yi,Liang, Yong-Min

, p. 702 - 707 (2014/02/14)

Functionalized spiro-tetrahydro-β-carbolines were formed by an efficient gold(I)-catalyzed rearrangement reaction of alkynylaziridine indoles. The reaction involved a Friedel-Crafts type intramolecular reaction of alkynylaziridine indoles, following by hydroamination of aminoallene intermediate.
