958778-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 958778-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,8,7,7 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 958778-97:
(8*9)+(7*5)+(6*8)+(5*7)+(4*7)+(3*8)+(2*9)+(1*7)=267
267 % 10 = 7
So 958778-97-7 is a valid CAS Registry Number.

NEW MASKED BUILDING BLOCK FOR ISOPRENOID POLYENE CHAIN SYNTHESIS
Mandai, T.,Iuchi, Y.,Suzuki, K.,Kawada, M.,Otera, J.
, p. 4721 - 4724 (2007/10/02)
The new building blocks 2, 3, and 4 have been effectively synthesized starting from 2-hydroxymethyl-4-phenylthio-1-butene (1a).A convenient synthesis of retinoic acid methyl ester (9) using 2 is also described.
