Check Digit Verification of cas no

The CAS Registry Mumber 1262841-57-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,8,4 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1262841-57:
(9*1)+(8*2)+(7*6)+(6*2)+(5*8)+(4*4)+(3*1)+(2*5)+(1*7)=155
155 % 10 = 5
So 1262841-57-5 is a valid CAS Registry Number.

N-Heterocyclic carbene-catalyzed tandem aza-benzoin/Michael reactions: On site reversal of the reactivity of N-Boc imines

Wu, Ke-Jia,Li, Gong-Qiang,Li, Yi,Dai, Li-Xin,You, Shu-Li

, p. 493 - 495 (2011)

A tandem NHC-catalyzed aza-benzoin/Michael reaction has been developed as a method to efficiently produce dihydroindenones and pyrrolidinone-containing tricycles. The novel reaction pattern involves tert-butyl aryl(tosyl) methylcarbamates reacting as both
