Check Digit Verification of cas no

The CAS Registry Mumber 1888389-19-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,8,8,3,8 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1888389-19:
(9*1)+(8*8)+(7*8)+(6*8)+(5*3)+(4*8)+(3*9)+(2*1)+(1*9)=262
262 % 10 = 2
So 1888389-19-2 is a valid CAS Registry Number.

Novel synthesis of 4-or 6-substituted indirubin derivatives

Zhang, Aiying,Yu, Mingfeng,Lan, Tian,Liu, Zenglu,Mao, Zhenmin

experimental part, p. 3125 - 3134 (2010/12/24)

A simple and convenient route for synthesis of a series of 4-or 6-substituted indirubin derivatives by oxidation and subsequent condensation of indoxyl and isatin is described. Acidic reaction conditions are crucial to the condensation of 4-substituted derivatives, whereas for the condensation of 6-substituted derivatives, both acidic and basic conditions work well.
