Check Digit Verification of cas no

The CAS Registry Mumber 1236069-51-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,0,6 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1236069-51:
(9*1)+(8*2)+(7*3)+(6*6)+(5*0)+(4*6)+(3*9)+(2*5)+(1*1)=144
144 % 10 = 4
So 1236069-51-4 is a valid CAS Registry Number.

Enamine-based domino strategy for C-acylation/deacetylation of acetoacetamides: A practical synthesis of -keto amides

Angelov, Plamen

experimental part, p. 1273 - 1275 (2010/07/03)

A practical three-step route for C-acylation/deacetylation of acetoacetamides is described. Initial enamination of the acetoacetamides with Boc-monoprotected ethylenediamine provides β-enamino amides, which are acylated at the -carbon with excellent selectivity. The C-acylated derivatives undergo domino fragmentation in acidic media to give the corresponding β-keto amides accompanied by 2-methyl-4,5-dihydro-1H-imidazole. Georg Thieme Verlag Stuttgart.
