Check Digit Verification of cas no

The CAS Registry Mumber 1269020-45-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,0,2 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1269020-45:
(9*1)+(8*2)+(7*6)+(6*9)+(5*0)+(4*2)+(3*0)+(2*4)+(1*5)=142
142 % 10 = 2
So 1269020-45-2 is a valid CAS Registry Number.

Synthesis of tetrahydro-5-azaindoles and 5-azaindoles using Pictet-Spengler reaction - Appreciable difference in products using different acid catalysts

Shumaila, Abdullah M.A.,Puranik, Vedavati G.,Kusurkar, Radhika S.

experimental part, p. 936 - 942 (2011/03/19)

Pictet-Spengler condensation of 2-(aryl)-2-(1H-pyrrol-2-yl)ethanamines using conventional acid catalysts like TMSCl or TFA resulted in the formation of substituted 5-azaindoles involving a tandem one pot four steps reaction sequence. By contrast use of gl
