78121-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78121-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,2 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78121-18:
(7*7)+(6*8)+(5*1)+(4*2)+(3*1)+(2*1)+(1*8)=123
123 % 10 = 3
So 78121-18-3 is a valid CAS Registry Number.

, p. 271 - 274 (2007/10/02)
The Michael addition of 1-acetyl-3-indolinone to α, β-unsaturated aldehydes and ketones is described. The synthesis of a number of δ-carbolines that contain alkyl and aryl substituents in the 2 and 4 positions was realised on the basis of the resulting 1,
