Check Digit Verification of cas no

The CAS Registry Mumber 1620133-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1620133-40:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*3)+(3*3)+(2*4)+(1*0)=105
105 % 10 = 5
So 1620133-40-5 is a valid CAS Registry Number.

Synthesis and antiviral activity of amino-acid conjugates of glycyrrhetic acid

Baltine Jr.,Khudobko,Mikhailova,Baltina,Fedorova,Orshanskaya, Ya. A.,Zarubaev,Kiselev

, p. 473 - 477 (2014)

Conjugates of glycyrrhetic acid (GLA) with amino acids (L-isoleucine, -leucine, -valine, and -phenylalanine) were synthesized by the acid-chloride method using methyl or tert-butyl esters of the acids. Tests in MDCK cell culture showed that the GLA conjugate with phenylalanine exhibited high antiviral activity against influenza A/H1N1/pdm09 virus (ED50 = 4.4 μg/mL, SI = 161).
