Check Digit Verification of cas no

The CAS Registry Mumber 1401735-39-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,7,3 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1401735-39:
(9*1)+(8*4)+(7*0)+(6*1)+(5*7)+(4*3)+(3*5)+(2*3)+(1*9)=124
124 % 10 = 4
So 1401735-39-4 is a valid CAS Registry Number.

Chain-walking strategy for organic synthesis: Catalytic cycloisomerization of 1,n-dienes

supporting information, p. 16544 - 16547,4 (2020/09/15)

The catalytic construction of carbon-carbon bonds in small organic molecules via chain walking is described. Catalytic cycloisomerization of 1,n-dienes via chain walking was achieved using a palladium-1,10-phenanthroline catalyst to form five-membered-ring products. By means of a cycloisomerization/ hydrogenation protocol, 1,7- to 1,14-dienes were selectively converted to bicyclo[4.3.0]nonane derivatives. The use of chain walking provides a new method in organic synthesis to functionalize unreactive carbon-hydrogen bonds by letting the catalyst look for preferable bond-forming sites by moving around on the substrate.
