Check Digit Verification of cas no

The CAS Registry Mumber 1242078-10-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,0,7 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1242078-10:
(9*1)+(8*2)+(7*4)+(6*2)+(5*0)+(4*7)+(3*8)+(2*1)+(1*0)=119
119 % 10 = 9
So 1242078-10-9 is a valid CAS Registry Number.

ZrOCl2?8H2O as an efficient catalyst for the pseudo four-component synthesis of benzopyranopyrimidines

Tavakoli, Hamid Reza,Moosavi, Sayed Mojtaba,Bazgir, Ayoob

, p. 260 - 263 (2013/07/26)

An efficient and environmentally benign protocol for the pseudo four-component synthesis of benzopyranopyrimidines via condensation of salicylic aldehydes, malononitrile and various amines catalyzed by ZrOCl2?8H2O as an inexpensive and eco-friendly catalyst with high catalytic activity under solvent-free conditions is reported. This protocol provides a new and improved method for obtaining benzopyranopyrimidines in terms of good yields, simple experimental procedure and short reaction time.
