Check Digit Verification of cas no

The CAS Registry Mumber 1292358-61-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,3,5 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1292358-61:
(9*1)+(8*2)+(7*9)+(6*2)+(5*3)+(4*5)+(3*8)+(2*6)+(1*1)=172
172 % 10 = 2

"On water"-promoted direct alkynylation of isatins catalyzed by NHC-silver complexes for the efficient synthesis of 3-hydroxy-3-ethynylindolin- 2-ones

Fu, Xiao-Pu,Liu, Li,Wang, Dong,Chen, Yong-Jun,Li, Chao-Jun

supporting information; experimental part, p. 549 - 553 (2011/05/03)

The direct alkynylation of isatins catalyzed by NHC-Ag complexes via the activation of alkyne C-H bond on water was developed for the efficient synthesis of 3-hydroxy-3-ethynylindolin-2-ones under an air atmosphere. A remarkable rate-enhancement by water
