Check Digit Verification of cas no

The CAS Registry Mumber 170877-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,8,7 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 170877-03:
(8*1)+(7*7)+(6*0)+(5*8)+(4*7)+(3*7)+(2*0)+(1*3)=149
149 % 10 = 9
So 170877-03-9 is a valid CAS Registry Number.

Generation of chiral (η5-indenyl)2(η3-allyl)Ti complex and its highly enantioselective reaction with carbonyl compounds

Urabe, Hirokazu,Yoshikawa, Kaoru,Sato, Fumie

, p. 5595 - 5598 (2007/10/03)

The (η5-indenyl)2(η3-2-alkyl-1-methylallyl)Ti complex 10, successfully generated from (η5-indenyl)2TiCl2 8, 2-alkylbutadiene, and i-PrMgCl, reached with carbon dioxide or RCHO (R = Ph, ET, i-Pr, or t-Bu) to give the corresponding optically active β,γ-unsaturated carboxylic acid 11 or threohomoallyl alcohols 12-15 with high enantiomeric purities of up to 96%.
