Check Digit Verification of cas no

The CAS Registry Mumber 283157-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,3,1,5 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 283157-03:
(8*2)+(7*8)+(6*3)+(5*1)+(4*5)+(3*7)+(2*0)+(1*3)=139
139 % 10 = 9
So 283157-03-9 is a valid CAS Registry Number.

Enantioselective Strecker-type reaction promoted by polymer-supported bifunctional catalyst

Nogami, Hiroyuki,Matsunaga, Shigeki,Kanai, Motomu,Shibasaki, Masakatsu

, p. 279 - 283 (2001)

The JandaJEL-supported bifunctional catalyst 3 (10 mol%) promoted the Strecker-type reaction of aromatic and α,β-unsaturated imines in excellent yields with 83-87% ee in the presence of 'BuOH (110 mol%). The reactivity of 3 was comparable to the homogeneous analogue 1, and 3 could be recycled at least four times.

Chiral lanthanum(III)-binaphthyldisulfonate complexes for catalytic enantioselective strecker reaction

Hatano, Manabu,Hattori, Yasushi,Furuya, Yoshiro,Ishihara, Kazuaki

supporting information; experimental part, p. 2321 - 2324 (2009/10/02)

A catalytic enantioselective Strecker reaction catalyzed by novel chiral lanthanum(III)-binaphthyl disulfonate complexes was developed. The key to promoting the reactions was a semistoichiometric amount of AcOH or i-PrCO2H, which takes advantage of HCN ge

A Catalytic asymmetric strecker-type reaction: Interesting reactivity difference between TMSCN and HCN
