Check Digit Verification of cas no

The CAS Registry Mumber 228704-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,7,0 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 228704-07:
(8*2)+(7*2)+(6*8)+(5*7)+(4*0)+(3*4)+(2*0)+(1*7)=132
132 % 10 = 2
So 228704-07-2 is a valid CAS Registry Number.

Catalytic dehydrogenative N-((triisopropylsilyl)oxy)carbonyl (Tsoc) protection of amines using iPr3SiH and CO2

Tanaka,Yamamura,Nakane,Kitamura

, p. 13110 - 13112 (2015)

A versatile method has been found to catalyze the dehydrogenative N-((triisopropylsilyl)oxy)carbonyl (Tsoc) protection of amines using Pd/C, volatile iPr3SiH and CO2 gas without the liberation of any salts. A simple filtration/evaporation process facilitates the easy isolation of the product, thereby enhancing the utility of Tsoc as an amine-protecting group in organic synthesis.
