Check Digit Verification of cas no

The CAS Registry Mumber 19894-78-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,9 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19894-78:
(7*1)+(6*9)+(5*8)+(4*9)+(3*4)+(2*7)+(1*8)=171
171 % 10 = 1
So 19894-78-1 is a valid CAS Registry Number.

Preparation of the geranyl-α-pyrone (±)-aurantiacone via a new pyrone synthesis

Schmidt, Dietmar,Conrad, Jürgen,Klaiber, Iris,Mika, Sabine,Beifuss, Uwe

, p. 333 - 335 (2007)

The structure of the leaf resin geranyl-α-pyrone auranti-acone isolated from Mimulus (= Diplacus) aurantiacus (Curtis) Jeps. (Scrophulariaceae) was confirmed through synthesis. The key step is lactonization of the sensitive 5-hydroxy-3-oxopent-4-enoic acid under mild conditions, which can be released from the corresponding bispotassium salt. The latter is accessible in a few steps from an N-acyl aziridine and an ethyl acetoacetate. Georg Thieme Verlag Stuttgart.
