807378-02-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 807378-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,7,3,7 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 807378-02:
(8*8)+(7*0)+(6*7)+(5*3)+(4*7)+(3*8)+(2*0)+(1*2)=175
175 % 10 = 5
So 807378-02-5 is a valid CAS Registry Number.

, p. 4257 - 4259 (2004)
(Chemical Equation Presented) 2′,3′-Dideoxy-6′,6′- difluorouracils, a novel series of gem-difluoromethylenated carbocyclic nucleosides, were synthesized from (Z)-but-2-ene-1,4-diol in 14 steps. A notable step was the construction of the carbocyclic ring v
