Check Digit Verification of cas no

The CAS Registry Mumber 1279575-79-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,9,5,7 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1279575-79:
(9*1)+(8*2)+(7*7)+(6*9)+(5*5)+(4*7)+(3*5)+(2*7)+(1*9)=219
219 % 10 = 9
So 1279575-79-9 is a valid CAS Registry Number.

Core-structure-motivated design of a phosphine-catalyzed [3 + 2] cycloaddition reaction: Enantioselective syntheses of spirocyclopenteneoxindoles

Tan, Bin,Candeias, Nuno R.,Barbas, Carlos F.

, p. 4672 - 4675 (2011/06/19)

A novel organocatalytic asymmetric [3 + 2] cycloaddition reaction between methyleneindolinones and allylic compounds yielding complex spirocyclopentaneoxindoles has been developed. It provides extraordinary levels of enantioselective control involving a c
