Check Digit Verification of cas no

The CAS Registry Mumber 108385-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,3,8 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 108385-63:
(8*1)+(7*0)+(6*8)+(5*3)+(4*8)+(3*5)+(2*6)+(1*3)=133
133 % 10 = 3
So 108385-63-3 is a valid CAS Registry Number.

New Approaches to the Synthesis of trans-Alkene Isosteres of Dipeptides

Spaltenstein, Andreas,Carpino, Philip A.,Miyake, Fumio,Hopkins, Paul B.

, p. 3759 - 3766 (2007/10/02)

Two new syntheses of protected dipeptide analogues bearing a trans carbon-carbon double bond in place of the amide linkage are reported.One route is a linear synthesis employing the rearrangement of an allylic selenide to a protected allylic amine.The second route is convergent and uses the Julia olefin synthesis in a key step.The latter route is fully stereocontrolled and has been used to prepare protected trans-alkene isosteres of the dipeptides TyrAla, PhePhe, LeuPhe, and LeuLeu.
