Check Digit Verification of cas no
The CAS Registry Mumber 1035803-72-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,5,8,0 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1035803-72:
(9*1)+(8*0)+(7*3)+(6*5)+(5*8)+(4*0)+(3*3)+(2*7)+(1*2)=125

A one pot procedure for the synthesis of α-hydroxyamides from the corresponding α-hydroxyacids
Kelly,LaCour
, p. 859 - 869 (1992)
α-Hydroxyamides are synthesized from the corresponding α-hydroxyacids by generation of the bis-trimethylsilyl derivative and treating it with oxalyl chloride. Following addition of the appropriate amine, the TMS ether is hydrolized in the workup to provid
