Check Digit Verification of cas no

The CAS Registry Mumber 608523-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,8,5,2 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 608523-23:
(8*6)+(7*0)+(6*8)+(5*5)+(4*2)+(3*3)+(2*2)+(1*3)=145
145 % 10 = 5
So 608523-23-5 is a valid CAS Registry Number.

Synthesis of 9-substituted tetrahydrodiazepinopurines - Asmarine A analogues

Pappo, Doron,Kashman, Yoel

, p. 6493 - 6501 (2007/10/03)

Asmarines are marine alkaloids, with a unique tetrahydro[1,4]diazepino-[1,2,3-g,h]purine (THDAP) structure and interesting biological properties. Three synthetic approaches were employed for the preparation of the THDAP system. Several N-9, of the purine, protecting groups were investigated. 15N-Chemical shifts measured from 15NH HMBC experiments for several compounds, that demonstrate the influence of various structural features on the 15N-resonances are reported.
