Check Digit Verification of cas no

The CAS Registry Mumber 502627-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,6,2 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 502627-80:
(8*5)+(7*0)+(6*2)+(5*6)+(4*2)+(3*7)+(2*8)+(1*0)=127
127 % 10 = 7
So 502627-80-7 is a valid CAS Registry Number.

Practical synthesis of a highly functionalized thiazole ketone

Frey, Lisa F.,Marcantonio, Karen M.,Chen, Cheng-Yi,Wallace, Debra J.,Murry, Jerry A.,Tan, Lushi,Chen, Weirong,Dolling, Ulf H.,Grabowski, Edward J. J.

, p. 6363 - 6373 (2007/10/03)

Compound 1 is a uniquely substituted ketone prepared via addition of a thiazole anion to an aromatic nitrile in good overall yield. An exploration into the generality of the addition of thiazole anions to nitriles allowed us to make a variety of thiazole ketones in good to excellent yields. The non-odorous thiolate-mediated demethylation reaction used in the synthesis of 1 is also presented.
