Check Digit Verification of cas no

The CAS Registry Mumber 25634-92-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,3 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25634-92:
(7*2)+(6*5)+(5*6)+(4*3)+(3*4)+(2*9)+(1*2)=118
118 % 10 = 8
So 25634-92-8 is a valid CAS Registry Number.

A versatile palladium catalyst system for Suzuki-Miyaura coupling of alkenyl tosylates and mesylates

Wong, Pui Yu,Chow, Wing Kin,Chung, Kin Ho,So, Chau Ming,Lau, Chak Po,Kwong, Fuk Yee

supporting information; experimental part, p. 8328 - 8330 (2011/09/14)

A general and effective palladium system for Suzuki-Miyaura coupling of alkenyl electrophiles under mild reaction conditions is reported. With the Pd(OAc)2/CM-phos system, a variety of alkenyl tosylates are coupled well with ArB(OH)2. Moreover, the first successful examples of using alkenyl mesylates in alkenylation are also described.
