Check Digit Verification of cas no

The CAS Registry Mumber 850211-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,2,1 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 850211-90:
(8*8)+(7*5)+(6*0)+(5*2)+(4*1)+(3*1)+(2*9)+(1*0)=134
134 % 10 = 4
So 850211-90-4 is a valid CAS Registry Number.

"On water"-promoted direct coupling of indoles with 1,4-benzoquinones without catalyst

Zhang, Hai-Bo,Liu, Li,Chen, Yong-Jun,Wang, Dong,Li, Chao-Jun

, p. 869 - 873 (2007/10/03)

A highly efficient direct coupling of indole compounds with 1,4-benzoquinones was developed "on water" in the absence of any catalyst, organic co-solvent, or additives. The "on-water" conditions provided the best yields of the corresponding products and the only system to produce bis(coupling) products. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
