Check Digit Verification of cas no

The CAS Registry Mumber 1402140-47-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,1,4 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1402140-47:
(9*1)+(8*4)+(7*0)+(6*2)+(5*1)+(4*4)+(3*0)+(2*4)+(1*7)=89
89 % 10 = 9
So 1402140-47-9 is a valid CAS Registry Number.

One-pot syntheses of novel pyrazole-containing bisphosphonate esters at room temperature

Xiang, Haoyue,Qi, Xueyu,Xie, Yuyuan,Xu, Guangyu,Yang, Chunhao

, p. 7730 - 7738 (2013/04/23)

An efficient general synthetic approach has been developed to synthesize pyrazole-containing bisphosphonate (N-BPs) esters from chromenone derivatives via a sequential two-step reaction in one pot at ambient temperature in good to excellent yields. This protocol provides a new convenient method to prepare lipophilic bisphosphonate precursors with potential activities. The Royal Society of Chemistry 2012.
