Check Digit Verification of cas no

The CAS Registry Mumber 157252-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,2,5 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 157252-28:
(8*1)+(7*5)+(6*7)+(5*2)+(4*5)+(3*2)+(2*2)+(1*8)=133
133 % 10 = 3
So 157252-28-3 is a valid CAS Registry Number.

Intermolecular photoaddition reaction of arenecarbothioamides to 2- methoxy- and 2-trimethylsiloxyfurans. Facile synthesis of arene-fused aminobenzoates by novel photoinduced benzannulation

Oda, Kazuaki,Sakai, Masayuki,Machida, Minoru

, p. 584 - 589 (2007/10/03)

Irradiation of arenecarbothioamides with 2-methoxyfuran in benzene solution gave arene-fused aminobenzoates in moderate yields accompanied by small amounts of arylpyrroles or arylthiophenes. In the case of 2- trimethylsiloxyfuran, arenecarbothioamides gave arene-fused aminobenzoates in good yields as sole products. It was demonstrated that certain furan derivatives are potentially useful as building blocks in photoinduced benzannulation.

Benzannulation of Heteroaromatics by Photoreaction of Arenecarbothioamides with 2-Methoxyfuran

Oda, Kazuaki,Machida, Minoru

, p. 1477 - 1478 (2007/10/02)

Irradiation of arenecarbothioamides 1 with 2-methoxyfuran 2 in benzene solution gives benzo-fused arene derivatives 3 in moderate yields.
