98849-31-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98849-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,4 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98849-31:
(7*9)+(6*8)+(5*8)+(4*4)+(3*9)+(2*3)+(1*1)=201
201 % 10 = 1
So 98849-31-1 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).
