Check Digit Verification of cas no

The CAS Registry Mumber 1489100-10-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,8,9,1,0 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1489100-10:
(9*1)+(8*4)+(7*8)+(6*9)+(5*1)+(4*0)+(3*0)+(2*1)+(1*0)=158
158 % 10 = 8
So 1489100-10-8 is a valid CAS Registry Number.

One-pot synthesis of functionalized 2,5-dihydrofurans via an amine-promoted Petasis borono-Mannich reaction

Cui, Chun-Xiao,Li, Hui,Yang, Xian-Jin,Yang, Jun,Li, Xiao-Qiang

supporting information, p. 5944 - 5947 (2014/01/06)

A series of functionalized 2,5-dihydrofurans were efficiently synthesized via an amine-promoted Petasis borono-Mannich reaction of 4-substituted 1,2-oxaborol-2(5H)-ols with salicylaldehydes in high yields. The process, which combines a boronic acid-based Mannich reaction and a highly efficient intramolecular SN2 cyclization, provides a one-step and efficient route toward 2,5-dihydrofurans from simple and stable starting materials.
