Check Digit Verification of cas no

The CAS Registry Mumber 455334-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,5,3,3 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 455334-17:
(8*4)+(7*5)+(6*5)+(5*3)+(4*3)+(3*4)+(2*1)+(1*7)=145
145 % 10 = 5
So 455334-17-5 is a valid CAS Registry Number.

Enantioselective synthesis of 4-hydroxy-D-pyroglutamic acid derivatives by an asymmetric 1,3-dipolar cycloaddition

Merino, Pedro,Revuelta, Julia,Tejero, Tomas,Chiacchio, Ugo,Rescifina, Antonio,Piperno, Anna,Romeo, Giovanni

, p. 167 - 172 (2002)

The 1,3-dipolar cycloaddition of a chiral nitrone derived from glyoxylic acid and protected D-ribosyl hydroxylamine with the acrylamide of Oppolzer's sultam provides a perfectly stereoselective approach to protected (2R,4R)-4-hydroxy-D-pyroglutamic acid.
