Check Digit Verification of cas no

The CAS Registry Mumber 188965-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,6 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 188965-82:
(8*1)+(7*8)+(6*8)+(5*9)+(4*6)+(3*5)+(2*8)+(1*2)=214
214 % 10 = 4
So 188965-82-4 is a valid CAS Registry Number.

Convenient synthesis of retinol-related polyenes through hydroxyalkylation of 3-sulfolenes

Subramanian,Chou,Bhat

, p. 2787 - 2793 (2001)

Convenient synthesis of retinol-related polyenes is described through hydroxyalkylation of 3-sulfolenes followed by onepot desulfonylation and dehydration in the presence of POC13/pyridine in toluene.

Short synthetic route to retinoids through dialkylation of 3-methyl-3-sulfolene

Subramanian,Padmakumar,Bhat, Sujata V.

, p. 2585 - 2586 (2007/10/03)

The C20-retinoid carbon skeleton has been synthesised through sequential alkylations of 3-methyl-3-sulfolene with bromomethyl methyl ether followed by C14-aldehyde to give dialkyl sulfolene which on further desulfonylation and dehydration yielded retinol methyl ether.
