Check Digit Verification of cas no

The CAS Registry Mumber 1027376-20-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,3,7 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1027376-20:
(9*1)+(8*0)+(7*2)+(6*7)+(5*3)+(4*7)+(3*6)+(2*2)+(1*0)=130
130 % 10 = 0
So 1027376-20-0 is a valid CAS Registry Number.

Solid-phase synthesis of N-aryl-N′-carboalkoxy guanidines by the mitsunobu reaction of Fmoc-guanidines

Robinson, Dale E.,Seth, Punit P.,Jefferson, Elizabeth A.

, p. 2743 - 2749 (2007/10/03)

A new method for the solid-phase synthesis of N-aryl-N′-carboalkoxy guanidines is described. Aromatic amines were reacted with Fmoc-isothiocyanate to provide Fmoc-thioureas, which were coupled with Rink amide resin to provide the corresponding resin-bound Fmoc-guanidines. Subsequent Mitsunobu alkylation with a variety of alcohols delivered N-aryl-N′ carboalkoxy guanidines in good to high purity after resin cleavage.
