Check Digit Verification of cas no

The CAS Registry Mumber 473273-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,2,7 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 473273-04:
(8*4)+(7*7)+(6*3)+(5*2)+(4*7)+(3*3)+(2*0)+(1*4)=150
150 % 10 = 0
So 473273-04-0 is a valid CAS Registry Number.

Corticosteroid decomposition via a mixed anhydride

Conrow, Raymond E.,Dillow, Glen W.,Bian, Liangqiao,Xue, Liang,Papadopoulou, Olga,Baker, John K.,Scott, Britt S.

, p. 6835 - 6836 (2002)

Oxidation of dexamethasone in an aqueous suspension by air during prolonged storage produces the 17α-formyloxy-17β-carboxylic acid 4. A pathway to 4 is proposed that involves Baeyer-Villiger-type oxidation of keto aldehyde 1 to mixed anhydride 5, followed by intramolecular formyl transfer. Synthetically, acid 3 was reacted with N,N′-carbonyldiimidazole followed by triethylammonium formate in order to generate the transient anhydride 5 en route to an authentic sample of 4.
