139416-86-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139416-86-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,1 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139416-86:
(8*1)+(7*3)+(6*9)+(5*4)+(4*1)+(3*6)+(2*8)+(1*6)=147
147 % 10 = 7
So 139416-86-7 is a valid CAS Registry Number.

Prop-2-ynylic Carbonates as a1,a2 Synthons in Palladium Catalysed Annulation Reactions with Bifunctional Nucleophiles
Geng, Lifeng,Lu, Xiyan
, p. 17 - 22 (2007/10/02)
Prop-2-ynylic carbonates were used as a1,a2 synthons in palladium catalysed annulation reactions with bifunctional nucleophiles.Methods were developed for the synthesis of 3-methylenedihydropyran derivatives and methylenecycloalkane
