Check Digit Verification of cas no

The CAS Registry Mumber 129503-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,0 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129503-31:
(8*1)+(7*2)+(6*9)+(5*5)+(4*0)+(3*3)+(2*3)+(1*1)=117
117 % 10 = 7
So 129503-31-7 is a valid CAS Registry Number.

Synthesis and chemical reactivity of C-5 substituted 6,7-bis-(hydroxymethyl)-1H-pyrrolizine biscarbamate tumor inhibitors [1]

Anderson,Mach

, p. 1025 - 1030 (1990)

A series of C-5 substituted pyrrolizine biscarbamate alkylating agents were synthesized and evaluated in an in vitro alkylation assay. Introduction of electron-withdrawing substituents at the C-5 position resulted in a dramatic decrease in chemical reactivity toward the model nucleophile 4-(4-nitrobenzyl)pyridine (NBP).
