Check Digit Verification of cas no

The CAS Registry Mumber 156545-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,4 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156545-99:
(8*1)+(7*5)+(6*6)+(5*5)+(4*4)+(3*5)+(2*9)+(1*9)=162
162 % 10 = 2
So 156545-99-2 is a valid CAS Registry Number.

Studies of Isocyanides and Related Compounds. Synthesis of a Novel Class of Furan Derivatives

Bossio, Ricardo,Marcaccini, Stefano,Pepino, Roberto

, p. 527 - 528 (2007/10/02)

The reaction between arenesulfonylacetic acids 1, arylglyoxals 2 and isocyanides 3 affords N-substituted 3-aryl-2-arylsulfonylacetoxy-3-oxopropionamides 4, which are cyclized to N-substituted 3-aryl-4-arylsulfonyl-2,5-dihydro-5-oxofuran-2-carboxamides 6.Treatment of compounds 6 with diazomethane affords N-substituted 3-aryl-4-arylsulfonyl-5-methoxyfuran-2-carboxamides 7, a novel class of furan derivatives. - Key Words: Isocyanides / Glyoxals / Passerine rections / Furans
