Check Digit Verification of cas no

The CAS Registry Mumber 76426-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76426-91:
(7*7)+(6*6)+(5*4)+(4*2)+(3*6)+(2*9)+(1*1)=150
150 % 10 = 0
So 76426-91-0 is a valid CAS Registry Number.

Synthesis of 2H-Chromenopyrimidine-2,4(3H)-diones (10-Oxa-5-deazaflavins) and Their Use in the Oxidation of Benzyl Alcohol

Yoneda, Fumio,Hirayama, Ryiochi,Yamashita, Machiko

, p. 301 - 304 (2007/10/02)

Treatment of 6-phenoxyuracil derivatives with the Vilsmeier reagent (dimethylformamide-phosphorous oxychloride)gave the corresponding 5-formyl-6-phenoxyuracil derivatives or their equivalents (5-dimethylaminomethylene-6-phenoxyuracil derivatives).Dehydrative cyclization of the above 5-formyluracils or 5-dimethylaminomethyleneuracils with polyphosphoric acid gave the corresponding 2H-chromenopyrimidine-2,4(3H)diones (10-oxa-5-deazaflavins).These 10-oxa-5-deazaflavins showed strong oxidizing power in oxidizing benzyl alcohol even under neutral conditions (without base) to give benzaldehyde, while they were hydrogenated to 1,5-dihydro-10-oxa-5-deazaflavins.
