Check Digit Verification of cas no

The CAS Registry Mumber 303176-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,7 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 303176-42:
(8*3)+(7*0)+(6*3)+(5*1)+(4*7)+(3*6)+(2*4)+(1*2)=103
103 % 10 = 3
So 303176-42-3 is a valid CAS Registry Number.

Synthesis of (S,R,R,R)-α,α′-iminobis(methylene)bis(6- fluoro-3H,4H-dihydro-2H-1-benzopyran-2-methanol)

Wang, Nai-Xing,Yu, An-Guang,Wang, Gui-Xia,Zhang, Xiu-Hui,Li, Qian-Shu,Li, Zhen

, p. 1154 - 1158 (2008/02/02)

The β1-adrenergic antagonist (S,R,R,R)-α, α′-iminobis(methylene)bis(6-fluoro-3H,4H-dihydro-2H-1-benzopyran-2- methanol) was synthesized from natural chiral pool starting materials through an efficient, convergent synthetic strategy. The cyclization mechanism of the key step was investigated using computer modeling and is discussed. Georg Thieme Verlag Stuttgart.
