Check Digit Verification of cas no

The CAS Registry Mumber 34182-93-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,8 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 34182-93:
(7*3)+(6*4)+(5*1)+(4*8)+(3*2)+(2*9)+(1*3)=109
109 % 10 = 9
So 34182-93-9 is a valid CAS Registry Number.

, p. 2087 - 2090 (2003)

(Matrix presented) High stereoselectivities were found in a wide range of superacid-catalyzed Pictet-Spengler cyclization reactions. Particularly in the cases of 2-alkyl-N-benzylidene-2-phenethylamines, an enhanced stereoselectivity was observed under the
