Check Digit Verification of cas no

The CAS Registry Mumber 37129-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,1,2 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 37129-22:
(7*3)+(6*7)+(5*1)+(4*2)+(3*9)+(2*2)+(1*2)=109
109 % 10 = 9
So 37129-22-9 is a valid CAS Registry Number.

Novel method for synthesis of aryl hydrazones from α-diazo esters: scope and limitations of nucleophiles

Yasui, Eiko,Wada, Masao,Takamura, Norio

scheme or table, p. 461 - 468 (2009/04/06)

Aryl hydrazones, the precursor of Fischer indole synthesis, were easily obtained by nucleophilic addition of aryllithium reagents to diazo esters. The aryl hydrazones were converted into indoles in good yields by heating with thionyl chloride in alcohol.
