Check Digit Verification of cas no

The CAS Registry Mumber 916140-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,1,4 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 916140-41:
(8*9)+(7*1)+(6*6)+(5*1)+(4*4)+(3*0)+(2*4)+(1*1)=145
145 % 10 = 5
So 916140-41-5 is a valid CAS Registry Number.

Design and synthesis of new spiroheterocycles: Selective role of potassium fluoride in DMF

Chande, Madhukar S.,Bhat, Udayashankar S.

, p. 1041 - 1047 (2007/10/03)

Potassium fluoride (KF) in dimethyl formamide (DMF) is found to be very effective and selective in the synthesis of spiro compounds. 4-Bromo-4-carbethoxy-(4H)-1-phenyl-3-substituted-pyrazol-5-ones 4 are selectively converted to spiro derivatives by reacti
