Check Digit Verification of cas no
The CAS Registry Mumber 173472-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,4,7 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 173472-38:
(8*1)+(7*7)+(6*3)+(5*4)+(4*7)+(3*2)+(2*3)+(1*8)=143
143 % 10 = 3
So 173472-38-3 is a valid CAS Registry Number.

Madder, A.,Muenster, I.,Rolle, U.,Clercq, P. J. De
, p. 613 - 622 (2007/10/03)
The synthesis of the enantiomerically pure bicyclic guanidines 3a and 3b is described.The convergent strategy is based on methodology developed by Schmidtchen.The therefore required amine components 6 and 9 obtained from methionine and L-glutamic acid, respectively.
