111652-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111652-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,5 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 111652-12:
(8*1)+(7*1)+(6*1)+(5*6)+(4*5)+(3*2)+(2*1)+(1*2)=81
81 % 10 = 1
So 111652-12-1 is a valid CAS Registry Number.

A convenient synthesis of N-Boc-protected tert-butyl esters of phenylglycines from benzylamines
Kise, Naoki,Ozaki, Hiroshi,Terui, Hiroaki,Ohya, Kengo,Ueda, Nasuo
, p. 7637 - 7639 (2007/10/03)
The N,N-di-Boc-protected benzylamines undergo [1,2] Boc migration on treatment with KDA/t-BuOLi. By this reaction, the corresponding N-Boc-protected t-butyl esters of phenylglycines are obtained in high yields.
