143643-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143643-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,4 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143643-03:
(8*1)+(7*4)+(6*3)+(5*6)+(4*4)+(3*3)+(2*0)+(1*3)=112
112 % 10 = 2
So 143643-03-2 is a valid CAS Registry Number.

Carbocyclic ring-enlarged oxetanocin analogues
Buenger, Greg S.,Marquez, Victor E.
, p. 3707 - 3710 (2007/10/02)
Carbocyclic versions of 2′,3′-dideoxy-3′C-hydroxymethyl nucleosides with adenine, guanine, uracil and cytosine bases were synthesized from a common cyclopentenone precursor. The extra hydroxymethyl moiety was introduced by photochemical addition of methan
