Check Digit Verification of cas no

The CAS Registry Mumber 139686-31-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,8 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139686-31:
(8*1)+(7*3)+(6*9)+(5*6)+(4*8)+(3*6)+(2*3)+(1*1)=170
170 % 10 = 0
So 139686-31-0 is a valid CAS Registry Number.

Stereoselective synthesis of alkenylated malonic diamide using masked acyl cyanide

Nemoto,Ibaragi,Bando,Kido,Shibuya

, p. 1319 - 1322 (1999)

A highly stereoselective synthesis of an alkenylated malonic diamide starting from a γ,δ-epoxy-α,β-unsaturated carboxamide was accomplished using the masked acyl cyanide (MAC: the protected hydroxymalonitrile) via palladium-catalyzed regio- and stereoselective carbon-carbon bond formation.

A facile chemoenzymatic route to optically active 4,5-disubstituted-2E-hexenoate derivastives. II

, p. 680 - 684 (2007/10/02)

The reaction of (±) methyl 4,5-trans-epoxy-(2E)-hexenoate (1) with nucleophiles having heteroatoms in the presence of BF3 · Et2O gave the 4,5-anti-5-hydroxy-4- and/or 2,5-anti-5-hydroxy-2-substituted products. Among them, the (±)-4,5
