Check Digit Verification of cas no

The CAS Registry Mumber 76374-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76374-20:
(7*7)+(6*6)+(5*3)+(4*7)+(3*4)+(2*2)+(1*0)=144
144 % 10 = 4
So 76374-20-4 is a valid CAS Registry Number.

Synthesis and absolute configuration of the first optically active organic molecule with T symmetry: (-)-1,3,5,7-tetrakis3-trishomocubanyl)acetoxy>methyl>adamantane

Nakazaki, Masao,Naemura, Koichiro

, p. 106 - 111 (1981)

By starting from the Diels-Alder adduct 12 between 2-(methoxycarbonyl)-1,4-benzoquinone (11) and cyclopentadiene, the modified Barborak synthesis of D3-trishomocubane afforded (-)-2-(1S,3S,5R,6S,8R,10R)-D3-trishomocubaneacetic acid (19) whose esterification with 1,3,5,7,-tetrakis(hydroxymethyl)adamantane (27) gave (-)-28, the first T symmetric organic molecule with known absolute configuration.
