123719-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123719-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,1 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123719-69:
(8*1)+(7*2)+(6*3)+(5*7)+(4*1)+(3*9)+(2*6)+(1*9)=127
127 % 10 = 7
So 123719-69-7 is a valid CAS Registry Number.

Smidrkal, Jan
, p. 3184 - 3192 (2007/10/02)
Alkaloids fagaronine (I), dihydrofagaronine (XXV) and oxyfagaronine (XXVI) were synthesized from 2,3-dihydroxynaphthalene (II) and 2-bromo-4,5-dimethoxybenzaldehyde (XI), the key synthetic steps being the preparation of 2-hydroxy-3-methoxy-5-nitronaphthal
