Check Digit Verification of cas no

The CAS Registry Mumber 3983-04-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,8 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3983-04:
(6*3)+(5*9)+(4*8)+(3*3)+(2*0)+(1*4)=108
108 % 10 = 8
So 3983-04-8 is a valid CAS Registry Number.

Allylic functionalization of unactivated olefins with grignard reagents

Bao, Hongli,Bayeh, Liela,Tambar, Uttam K.

supporting information, p. 1664 - 1668 (2014/03/21)

New advances in the functionalization of unactivated olefins with carbon nucleophiles have provided more efficient and practical approaches to convert inexpensive starting materials into valuable products. Recent examples have been reported with stabilized carbon nucleophiles, tethered carbon nucleophiles, diazoesters, and trifluoromethane donors. A general method for functionalizing olefins with aromatic, aliphatic, and vinyl Grignard reagents was developed. In a one-pot process, olefins are oxidized by a commercially available reagent to allylic electrophiles, which undergo selective copper-catalyzed allylic alkylation with Grignard reagents. Products are formed in high yield and with high regioselectivity. This was utilized to synthesize a series of skipped dienes, a class of compounds that are prevalent in natural products and are difficult to synthesize by known allylic alkylation methods. It all begins with olefins: Allylic functionalization with carbon nucleophiles is a powerful strategy for converting unactivated olefins into complex products.
