Check Digit Verification of cas no

The CAS Registry Mumber 130256-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,5 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130256-51:
(8*1)+(7*3)+(6*0)+(5*2)+(4*5)+(3*6)+(2*5)+(1*1)=88
88 % 10 = 8
So 130256-51-8 is a valid CAS Registry Number.

Addition of a tiglyltitanocene to chiral aldehydes: factors influencing simple and diastereofacial stereoselectivities

Szymoniak, Jan,Thery, Nadine,Moise, Claude

, p. 85 - 92 (2007/10/03)

The η3-tiglyltitanium(III) complex formed in situ from isoprene was reacted with a series of chiral aldehydes, some of which bear α- and/or β-benzyloxy groups, or a remote double bond. anti Diastereomeric homoallylic alcohols were formed stereospecifically starting from the alkoxy-free saturated aldehydes.In contrast, mixtures of anti and syn stereomers were obtained by using alkoxy- or ε-unsaturated aldehydes.The simple diastereoselectivities and diastereofacial selectivities observed are rationalized in terms of the chelation versus non-chelation-controlled process. - Keywords: η3-tiglyltitanocene complex; chiral aldehyde; stereoselectivity; chelation control
