Check Digit Verification of cas no

The CAS Registry Mumber 918957-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,9,5 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 918957-06:
(8*9)+(7*1)+(6*8)+(5*9)+(4*5)+(3*7)+(2*0)+(1*6)=219
219 % 10 = 9
So 918957-06-9 is a valid CAS Registry Number.

Solid-phase synthesis of tetrahydro-β-carbolines and tetrahydroisoquinolines by stereoselective intramolecular N-carbamyliminium pictet-spengler reactions

Diness, Frederik,Beyer, Juergen,Meldal, Morten

, p. 8056 - 8066 (2007/10/03)

A solid-phase method for the synthesis of tri-, tetra-, and pentacyclic compounds containing tetrahydro-β-carboline, tetrahydroisoquinoline or analogous scaffolds is presented. The reaction proceeds with high stereoselectivity through an intermediate N-ca
