Check Digit Verification of cas no

The CAS Registry Mumber 1254967-12-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,9,6 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1254967-12:
(9*1)+(8*2)+(7*5)+(6*4)+(5*9)+(4*6)+(3*7)+(2*1)+(1*2)=178
178 % 10 = 8
So 1254967-12-8 is a valid CAS Registry Number.

Indium-mediated allylation of aldehydes, ketones and sulfonimines with 2-(alkoxy)allyl bromides

Dhanjee, Heemal,Minehan, Thomas G.

supporting information; experimental part, p. 5609 - 5612 (2010/10/21)

2-(Alkoxy)propenyl bromides are readily prepared from 1,3-dibromo-2- propanol in a two-step sequence involving hydroxyl protection and sodium hydride-induced dehydrobromination. Indium-mediated allylation of aldehydes, ketones, and sulfonimines with 2-(alkoxy)propenyl bromides furnishes the corresponding homoallylic alcohols and sulfonamines in good yields. The products can be easily transformed into β-hydroxy ketones and esters, as well as substituted dihydropyrans, and protected β-amino acids. Chiral 2-(alkoxy)propenyl halides, derived from (-)-menthol and d-glucal, furnish diastereomerically enriched products.
