Check Digit Verification of cas no

The CAS Registry Mumber 1238840-23-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,8,8,4 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1238840-23:
(9*1)+(8*2)+(7*3)+(6*8)+(5*8)+(4*4)+(3*0)+(2*2)+(1*3)=157
157 % 10 = 7
So 1238840-23-7 is a valid CAS Registry Number.

Photodecarboxylative additions of N-protected α-amino acids to N-methylphthalimide

Gallagher, Sonia,Hatoum, Fadi,Zientek, Nicolai,Oelgem?ller, Michael

, p. 3639 - 3641 (2010)

Photoreactions involving N,N-dimethylated α-amino acid salts and N-methylphthalimide are dominated by photoreduction and acetone trapping. Only, N-phenyl glycinate underwent photodecarboxylative addition in a moderate yield of 30%. In contrast, N-acylated α-amino acid salts readily gave addition products in fair to high yields of 20-95%. Comparison experiments with N,N-dimethylacetamide and amino-/amido-containing phthalimides revealed the origin of the crucial electron-transfer step and the reactivity order NR 3 RCO2- ≥ RCONR2 was established.
