Check Digit Verification of cas no

The CAS Registry Mumber 1145779-74-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,5,7,7 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1145779-74:
(9*1)+(8*1)+(7*4)+(6*5)+(5*7)+(4*7)+(3*9)+(2*7)+(1*4)=183
183 % 10 = 3
So 1145779-74-3 is a valid CAS Registry Number.

Ionic liquid as an efficient promoting medium for synthesis of bis-pyrazolo[3,4-b:4′,3′-e]pyridines

Shi, Da-Qing,Yang, Fang

, p. 755 - 760 (2008)

The preparation of a series of bis-pyrazolo[3,4-b:4′,3′-e] pyridines by the reaction of 5-aminopyrazole with aldehydes in ionic liquid [bminiJBr is described. This new method has the advantages of easier work-up, milder reaction conditions, high yields and environmental friendliness compared with other methods.
