Check Digit Verification of cas no

The CAS Registry Mumber 74637-92-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,3 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74637-92:
(7*7)+(6*4)+(5*6)+(4*3)+(3*7)+(2*9)+(1*2)=156
156 % 10 = 6
So 74637-92-6 is a valid CAS Registry Number.

Improved synthesis of Watasenia preluciferin

Kakoi, Hisac,Inoue, Shoji

, p. 1669 - 1672 (2007/10/03)

On heating a mixture of 2-amino-3-benzyl-5-(p-hydroxyphenyl)pyrazine (2) and a large excess of p-hydroxyphenylpyruvic acid (4) at 130-140 °C in dioxane, without any reductive treatment, Watasenia preluciferin (1) was obtained directly in one batch process in 63% yield.

A NEW SYNTHESIS OF WATASENIA PRELUCIFERIN BY CYCLIZATION OF 2-AMINO-3-BENZYL-5-(p-HYDROXYPHENYL)PYRAZINE WITH p-HYDROXYPHENYLPYRUVIC ACID

Inoue, Shoji,Okada, Kunisuke,Tanino, Hideo,Kakoi, Hisae

, p. 299 - 300 (2007/10/02)

The reaction of 2-amino-3-benzyl-5-(p-hydroxyphenyl)pyrazine with p-hydroxyphenylpyruvic acid gave directly Watasenia preluciferin in a satisfactory yield without any reductive treatment.
