Check Digit Verification of cas no

The CAS Registry Mumber 90740-04-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,4 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90740-04:
(7*9)+(6*0)+(5*7)+(4*4)+(3*0)+(2*0)+(1*4)=118
118 % 10 = 8
So 90740-04-8 is a valid CAS Registry Number.

REACTIVE INTERMEDIATES IN THE PHOTOLYSIS AND THERMOLYSIS OF 3-CHLORO-3-BENZYLDIAZIRINE

Liu, Michael T. H.,Chishti, Najmul H.,Tencer, Michael,Tomioka, Hideo,Izawa, Yasuji

, p. 887 - 892 (1984)

The photochemical and thermal decomposition of 3-chloro-3-benzyldiazirine have been studied in different reaction conditions.The decomposition gives rise to benzylchlorocarbene which can rearrange to E and Z chlorostyrene and/or react with the environment.In the presence of acetic acid the main product is 1-chloro-2-phenylethyl acetate.Experiments with acetic acid-d4 showed that some of the chlorostyrene is formed from the carbocation; other experiments conducted with tetramethylethylene as a carbene trapping agent show that the carbene is formed even in the presence of acetic acid.
