Check Digit Verification of cas no

The CAS Registry Mumber 384820-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,4,8,2 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 384820-56:
(8*3)+(7*8)+(6*4)+(5*8)+(4*2)+(3*0)+(2*5)+(1*6)=168
168 % 10 = 8
So 384820-56-8 is a valid CAS Registry Number.

Derivatives of 17-(2-methylallyl)-substituted noroxymorphone: variation of the delta address and its effects on affinity and selectivity for the delta opioid receptor.

Ullrich,Dersch,Rothman,Jacobson,Rice

, p. 2883 - 2885 (2001)

In an effort to establish the importance of the N-(2-methylallyl) substituent in the noroxymorphone series, several derivatives have been synthesized, retaining that N-substituent and modifying the delta address moiety. A few compounds showed moderate binding affinity and selectivity for the delta receptor; none displayed a pharmacological profile as exceptional as N-(2-methylallyl)noroxymorphindole. A second study showed that 3-O-methylation of all derivatives decreases binding affinity. The present results indicate that only a combination of the N-(2-methylallyl) group and an indole delta address provided high selectivity for the delta receptor.
