Check Digit Verification of cas no

The CAS Registry Mumber 637025-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,0,2 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 637025-08:
(8*6)+(7*3)+(6*7)+(5*0)+(4*2)+(3*5)+(2*0)+(1*8)=142
142 % 10 = 2
So 637025-08-2 is a valid CAS Registry Number.

Stereospecific Pd(0)-Catalyzed Arylation of an Allylic Hydroxy Phosphonate Derivative: Formal Synthesis of (S)-(+)-ar-Turmerone

Rowe, Bradley J.,Spilling, Christopher D.

, p. 9502 - 9505 (2003)

Reaction of the (1S)-allylic hydroxy phosphonate 1(S) with methyl chloroformate in pyridine yields the corresponding carbonate 3(S). The carbonate 3(S) undergoes a palladium-catalyzed arylation with p-tolyl tributylstannane to give both the 1E and 1Z viny
