Check Digit Verification of cas no

The CAS Registry Mumber 1824-70-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1824-70:
(6*1)+(5*8)+(4*2)+(3*4)+(2*7)+(1*0)=80
80 % 10 = 0
So 1824-70-0 is a valid CAS Registry Number.

On the fluorescence detection of oxazepam and lorazepam with phthalaldehyde and analogues

Troschutz,Heinemann,Waibel,Troschutz

, p. 557 - 563 (2007/10/02)

Refluxing Oxazepam (1) and Lorazepam (2), resp., with ethanolic NaOH, followed by acid hydrolysis affords the 1,3-diamines 5 and 6. Cyclocondensation with phthalaldehyde (11a) and analogues 11b-e leads to fluorescent compounds of type 14 and 16. On the basis of these investigations a high specific TLC-fluorescence detection of Oxazepam (1) and Lorazepam is developed.
