Check Digit Verification of cas no

The CAS Registry Mumber 208347-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,3,4 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 208347-82:
(8*2)+(7*0)+(6*8)+(5*3)+(4*4)+(3*7)+(2*8)+(1*2)=134
134 % 10 = 4
So 208347-82-4 is a valid CAS Registry Number.

N,N-dibenzyloxycarbonylglycyl chloride as useful ketene equivalent in the synthesis of azetidin-2-ones

Cainelli, Gianfranco,Galletti, Paola,Giacomini, Daria

, p. 611 - 612 (2007/10/03)

N,N-3-Dibenzyloxycarbonylaminoazetidin-2-ones have been conveniently prepared from N,N-dibenzyloxycarbonylglycyl chloride and imines or hexahydrotriazines. The β-lactams thus obtained could be monodeprotected by mild hydrogenolysis with Pd on carbon.
