Check Digit Verification of cas no

The CAS Registry Mumber 1235548-25-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,5,4 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1235548-25:
(9*1)+(8*2)+(7*3)+(6*5)+(5*5)+(4*4)+(3*8)+(2*2)+(1*5)=150
150 % 10 = 0
So 1235548-25-0 is a valid CAS Registry Number.

Gold-catalyzed direct cycloketalization of acetonide-tethered alkynes in the presence of water

Alcaide, Benito,Almendros, Pedro,Carrascosa, Rocío

, p. 9391 - 9396 (2012/11/13)

A methodology for the direct preparation of bridged acetals from acetonide-tethered alkynes under gold catalysis in the presence of water has been developed. The bicyclic ring structures bearing a bridged five-membered ring arise from the regioselective b

Gold/acid-cocatalyzed regiodivergent preparation of bridged ketals via direct bis-oxycyclization of alkynic acetonides

Alcaide, Benito,Almendros, Pedro,Carrascosa, Rocio,Torres, M. Rosario

supporting information; experimental part, p. 1277 - 1283 (2010/07/03)

The regioselective metal/acid co-catalyzed direct bis-oxycyclization of alkynyldioxolanes allows the efficient synthesis of optically pure biand tricyclic bridged acetal systems.
