851762-30-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 851762-30-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,7,6 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 851762-30:
(8*8)+(7*5)+(6*1)+(5*7)+(4*6)+(3*2)+(2*3)+(1*0)=176
176 % 10 = 6
So 851762-30-6 is a valid CAS Registry Number.

, p. 2559 - 2562 (2007/10/03)
Base-mediated and/or palladium(0)-catalysed bis(allylation) of alkyl 2-(tolylsulfonyl)acetates gives 1,6-dienes, which upon ozonolytic cleavage of the double bonds and ammonolysis give 2,6-disubstituted pyridine-4-carboxylic esters. Decarboxylation of one
