Check Digit Verification of cas no

The CAS Registry Mumber 849727-15-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,7,2 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 849727-15:
(8*8)+(7*4)+(6*9)+(5*7)+(4*2)+(3*7)+(2*1)+(1*5)=217
217 % 10 = 7
So 849727-15-7 is a valid CAS Registry Number.

Efficient synthesis of bicyclic oxazolino- and thiazolino[3,2-c]pyrimidine- 5,7-diones and its application to the synthesis of GnRH antagonists

Pontillo, Joseph,Chen, Chen

, p. 1407 - 1411 (2005)

Treatment of various 2-methyl oxazolines or thiazolines with chlorocarbonyl isocyanate gives the corresponding bicyclic oxazolino- or thiazolino[3,2-c] pyrimidin-5,7-dione derivatives in very good yield. This reaction has been applied to the rapid syntheses of human gonadotropin-releasing hormone (hGnRH) receptor antagonists for SAR study, resulting in 13e with binding affinity in the low nanomolar range (4.5 nM).
