Check Digit Verification of cas no

The CAS Registry Mumber 791808-24-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,1,8,0 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 791808-24:
(8*7)+(7*9)+(6*1)+(5*8)+(4*0)+(3*8)+(2*2)+(1*4)=197
197 % 10 = 7
So 791808-24-7 is a valid CAS Registry Number.

Caged trans-4-hydroxy-2-nonenal

Brinson, Robert G.,Jones, Paul B.

, p. 3767 - 3770 (2004)

(Chemical Equation Presented) A caged 4-hydroxy-2-nonenal (4-HNE) has been prepared and its photochemistry investigated. Upon photolysis, 1 releases 4-HNE in up to 100% yield. From these photolyses, 4-HNE could be isolated in up to 91% yield. 4-HNE is produced under either aerobic or anaerobic conditions. The caging strategy does not require prior preparation of 4-HNE and, therefore, represents a three-step synthetic route to the bioactive enal in 48% overall yield.
