116679-89-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116679-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,6,7 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116679-89:
(8*1)+(7*1)+(6*6)+(5*6)+(4*7)+(3*9)+(2*8)+(1*9)=161
161 % 10 = 1
So 116679-89-1 is a valid CAS Registry Number.

EXTENDED SCOPE OF THE GRIGNARD REACTION OF β-HALOACETALS. USE OF ACYCLIC ACETALS
Greiner, A.
, p. 3547 - 3550 (2007/10/02)
Careful control of reaction conditions permits the high yield preparation of Grignard reagents fron β-halogenoacetals and their condensation with carbonyl compounds, regardless of the halogen (bromine, chlorine) or acetal structure (cyclic, acyclic).
