Check Digit Verification of cas no

The CAS Registry Mumber 105048-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,4 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105048-55:
(8*1)+(7*0)+(6*5)+(5*0)+(4*4)+(3*8)+(2*5)+(1*5)=93
93 % 10 = 3
So 105048-55-3 is a valid CAS Registry Number.

PHOTOCHEMICAL REACTION OF 2-ALKENOYL-3-ALKOXY-1,4-BENZOQUINONES. FORMATION OF 5H-PYRANOBENZODIOXIN DERIVATIVES

Maruyama, Kazuhiro,Iwamoto, Hidetoshi,Soga, Osamu,Takuwa, Akio,Osuka, Atsuhiro

, p. 1675 - 1678 (2007/10/02)

A number of 3-alkoxy-5-methyl-2-(α-methylcinnamoyl)-1,4-benzoquinones have been prepared by the reaction of 5-methyl-2-(α-methylcinnamoyl)-1,4-benzoquinone with alcohols.Irradiation of 3-methoxy-, 3-ethoxy-, and 3-isopropoxy-5-methyl-2-(α-methylcinnamoyl)-1,4-benzoquinones in solution gave 5H-pyranobenzodioxins.
