Check Digit Verification of cas no

The CAS Registry Mumber 1197026-56-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,0,2 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1197026-56:
(9*1)+(8*1)+(7*9)+(6*7)+(5*0)+(4*2)+(3*6)+(2*5)+(1*6)=164
164 % 10 = 4
So 1197026-56-4 is a valid CAS Registry Number.

Use of the SPhos ligand to suppress racemization in arylpinacolboronate ester Suzuki couplings involving α-amino acids. Synthesis of biaryl derivatives of 4-hydroxyphenylglycine, tyrosine, and tryptophan

Prieto, Monica,Mayor, Silvia,Lloyd-Williams, Paul,Giralt, Ernest

, p. 9202 - 9205 (2009)

(Chemical Equation Presented) α-Amino acid derivatives, particularly those of phenylglycine, can suffer significant racemization in Suzuki couplings. When arylpinacolboronate esters are used as coupling partners this unwanted side reaction can be suppress
