Check Digit Verification of cas no

The CAS Registry Mumber 1581705-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,1,7,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1581705-40:
(9*1)+(8*5)+(7*8)+(6*1)+(5*7)+(4*0)+(3*5)+(2*4)+(1*0)=169
169 % 10 = 9
So 1581705-40-9 is a valid CAS Registry Number.

Copper-catalyzed oxidative coupling of formamides with salicylaldehydes: Synthesis of carbamates in the presence of a sensitive aldehyde group

Barve, Balaji D.,Wu, Yang-Chang,El-Shazly, Mohamed,Chuang, Da-Wei,Cheng, Yuan-Bin,Wang, Jeh-Jeng,Chang, Fang-Rong

, p. 3206 - 3214 (2014)

A diverse library of novel carbamates was synthesized utilizing copper-catalyzed oxidative C-O coupling of formamides and salicylaldehydes. Sensitive aldehyde groups remained intact in the presence of an oxidant and a transition-metal salt. Salicylaldehydes bearing electron-donating, electron-withdrawing, and halogen groups as well as 1-hydroxy-2-naphthaldehydes provided the desired carbamates in good to excellent yields.
