Check Digit Verification of cas no

The CAS Registry Mumber 27570-06-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,5,7 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 27570-06:
(7*2)+(6*7)+(5*5)+(4*7)+(3*0)+(2*0)+(1*6)=115
115 % 10 = 5
So 27570-06-5 is a valid CAS Registry Number.

A simple and facile method for regio- and stereoselective bromoformyloxylation and bromoacetoxylation of olefins using NH4Br and oxone

supporting information, p. 3926 - 3933 (2014/07/08)

A mild and efficient protocol for the preparation of bromoformates as well as bromoacetates from olefins using NH4Br and oxone in nucleophile sources (DMF or DMA) without employing catalyst at room temperature is described. This method is facile, environmentally friendly and cost effective. A variety of terminal, internal and cyclic alkenes reacted smoothly to give the corresponding bromoformate and acetate products in good to excellent yields. Moreover, 1,2-disubstituted olefins provided moderate to excellent diastereoselectivity.
