Check Digit Verification of cas no

The CAS Registry Mumber 477808-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,8,0 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 477808-31:
(8*4)+(7*7)+(6*7)+(5*8)+(4*0)+(3*8)+(2*3)+(1*1)=194
194 % 10 = 4
So 477808-31-4 is a valid CAS Registry Number.

Chemoenzymatic syntheses of polyamines and tetraazamacrocycles

Rubio, Mercedes,Astorga, Covadonga,Alfonso, Ignacio,Rebolledo, Francisca,Gotor, Vicente

, p. 2441 - 2452 (2002)

Syntheses of different open chain polyamines starting from enzymatically prepared bis(amidoesters) are described. Some of these polyamines are also used as precursors in the syntheses of tetraazamacrocycles. This methodology can also be applied to the synthesis of chiral compounds.
