Check Digit Verification of cas no
The CAS Registry Mumber 4962-78-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,6 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4962-78:
(6*4)+(5*9)+(4*6)+(3*2)+(2*7)+(1*8)=121
121 % 10 = 1
So 4962-78-1 is a valid CAS Registry Number.

Regioselective pyrrole synthesis from asymmetric β-diketone and conversion to sterically hindered porphyrin
Fujii, Hiroshi,Yoshimura, Tetsuhiko,Kamada, Hitoshi
, p. 1427 - 1430 (1997)
The condensation of asymmetric β-diketones with α-oximinoacetoacetate esters affords pyrroles regioselectively. The mechanism of the regioselectivity is studied using 13C-NMR spectroscopy. Pyrrole having a neopentyl group at the 4-position is synthesized by the method, and further converted to a steric hindered porphyrin in good yield.
