Check Digit Verification of cas no

The CAS Registry Mumber 15849-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,8,4 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15849-25:
(7*1)+(6*5)+(5*8)+(4*4)+(3*9)+(2*2)+(1*5)=129
129 % 10 = 9
So 15849-25-9 is a valid CAS Registry Number.

Divergent dehydrogenative coupling of indolines with alcohols

Jiang, Xue,Tang, Weijun,Xue, Dong,Xiao, Jianliang,Wang, Chao

, p. 1831 - 1835 (2017/08/01)

The dehydrogenative coupling of indolines with alcohols catalyzed by an iridium complex has been achieved to afford both N- and C3-alkylated indoles selectively, by simply changing the addition time of a base additive. The iridacycle catalyst plays multiple roles in these reactions, which dehydrogenates both amines and alcohols and catalyzes the coupling reactions. Mechanistic studies reveal that a borrowing hydrogen-dehydrogenation process and a dehydrogenationborrowing hydrogen process are involved in N-alkylation and C3-alkylation reactions, respectively. The C3-alkylation reaction involves the direct coupling of two sp3 carbon centers.
