Check Digit Verification of cas no

The CAS Registry Mumber 62157-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,1,5 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 62157-91:
(7*6)+(6*2)+(5*1)+(4*5)+(3*7)+(2*9)+(1*1)=119
119 % 10 = 9
So 62157-91-9 is a valid CAS Registry Number.

A facile synthesis of stable precursors to 2-alkylated and 2,3-dialkylated 1,3-butadienes

Chou,Sun

, p. 1035 - 1038 (2007/10/02)

3-Sulfolenes 3, stable precursors to 2-alkylated and 2,3-dialkylated 1,3-butadienes, were prepared in good yield from (1) by regiospecific alkylation and reductive desulfurization.

Convenient Synthesis of 3-- and 3-Alkyl-Substituted 3-Sulfolenes

Tso, Hsi-Hwa,Chou, Ta-shue,Lai, Yu-Ling

, p. 4138 - 4141 (2007/10/02)

3--3-sulfolenes (5) were conveniently synthesized by a sequence of mesylation, elimination, and Michael addition reactions of 4-hydroxyalkylated 2-sulfolenes (2), which were prepared regioselectively via ultrasound-promoted allylzincation of 4-bromo-2-sulfolene (1). 3-Alkyl-3-sulfolenes were synthesized from desulfurization of 5.The application of the sequence was exemplified with the simple synthesis of α-myrcene.
