Check Digit Verification of cas no

The CAS Registry Mumber 74043-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,4 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74043-13:
(7*7)+(6*4)+(5*0)+(4*4)+(3*3)+(2*1)+(1*3)=103
103 % 10 = 3
So 74043-13-3 is a valid CAS Registry Number.

HIGHLY REGIOSELECTIVE DIELS-ALDER REACTIONS OF 2-TRIMETHYLSILYLMETHYL-1,3-BUTADIENE CATALYZED BY A LEWIS ACID AND APPLICATIONS TO SYNTHESES OF TERPENES

Hosomi, Akira,Iguchi, Hirokazu,Sasaki, Jun-ichi,Sakurai, Hideki

, p. 551 - 554 (2007/10/02)

2-Trimethylsilylmethyl-1,3-butadiene undergoes highly regioselective Diels-Alder reactions with dienophiles such as acrolein and methyl vinyl ketone catalyzed by aluminium chloride in which the "para" isomers are obtained almost exclusively.The adducts are converted readily to a variety of naturally occurring mono and sesquiterpenes.
