118974-34-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118974-34-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,7 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 118974-34:
(8*1)+(7*1)+(6*8)+(5*9)+(4*7)+(3*4)+(2*3)+(1*4)=158
158 % 10 = 8
So 118974-34-8 is a valid CAS Registry Number.

SYNTHESIS OF 2-(2-ALKOXYETHYLIDENE)-1,3-DIOXOLANES BY USING THE 1,3-DIOXOLANE RING AS A DOUBLE BOND DIRECTING GROUP
Aben, R. W. M.,Scheeren, J. W.
, p. 3597 - 3598 (2007/10/02)
The title compounds could be synthesized from 2-chloro-acetal precursors having a dioxolan ring as acetal function so that the double bond is directed towards the dioxolan ring.
